An example of the complete operation of the device of the imaging system and imaging according to the first variant implementation of the present invention will be described hereinafter with reference to Fig. 1-3, particularly with reference to Figure 3. After the irradiation conditions determined by the management computer 108 in response to an operation from the operator console 114 starts the image capture. The object is irradiated required radiation emitted from the device 110 for generating radiation, a managed device 109 radiation under certain irradiation conditions. The device 100 imaging displays image data corresponding to the radiation passed through the object. The output image data subjected to image processing in the control computer 108 and displayed in the device 113 display.

The control computer 108 requests the operator whether to continue capturing images. If the operator accepted the command not to continue the image capture (NO), the image capture is completed. If com is anyway to capture images taken from the operator (YES), the control computer 108 requests the operator should set the scan area. If the operator is accepted, the command does not switch the scan area (NO), the control computer 108 controls the device 109 radiation and a device 110 for generating radiation under conditions of image capture, which was defined for irradiating an object with radiation, again in the same conditions. If the command to switch the scan area is accepted from the operator (YES), the control computer 108 determines the scan area, which should be made the switch. In addition, the control computer 108 sends a control signal to induce the device 100 imaging to perform a switching operation, described in detail below, the device 100 of the imaging device 100 of the imaging performs the switching operation. After the switching operation is completed, the control computer 108 sends a control signal based on a specific area of the scan, the device 100 imaging to induce the device 100 imaging to perform the next image capture in a specific area of the scan.

Examples of the operation of the imaging system and imaging with the according to the first variant implementation of the present invention will be described hereinafter with reference to Fig. 4A-4D. With reference to Figa, when the supply voltage Vs bias on the conversion element 201, the device 100 imaging performs an idling operation during the period of idling. In the operation of idling, at least, the operation K1 initialization is repeated many times in order to stabilize the changing characteristics of the FPD 104 caused by the beginning of the supply voltage Vs displacement. The initializing operation is an operation of the initial application of a bias voltage to the conversion element before the accumulation operation to initialize the conversion element. In the example on Figa, a pair of operations W1 and accumulation operation K1 initialization is repeated many times as the operation of idling.

FIGU is a timing chart illustrating an example of operation of the device imaging during the period A-A' Figa. With reference to Figv, in operation W1 accumulation, the voltage Vss of narultimate is applied to the element 202 of the switching voltage Vs of the bias applied to the conversion element 201 for setting the switching elements in each pixel in a non-conductive state. When the operation K1 initialization, an integrating capacitor in the integrating amplifier 203 and the signal line are reset by the reset switch, and the voltage Vcom of the conductivity of relatives with circuit 102 excitation to the line G1 excitation, to set the switching elements with T11 on T1m in the first row in the conducting state. Setup items switch to the conducting state leads to initialize the Converter elements. Although the electrical charge of each Converter element is displayed with the corresponding switching element as an electric signal in this state, no data corresponding electrical signal is not output from the circuit 103 is read as the sampling frame and storage and subsequent schemes are not used in the first embodiment. An integrating capacitor and the signal line again later discharged for processing the output electrical signal. However, when data should be used for correction and so on, the scheme of sampling and storage and subsequent schemes can be implemented in some way, like the operation of the output image or operation of the output of the readout image, described below.

The repetition control the state of conduction of the switching element and the discharge from the first row to the n-th line makes FPD 104 to initialize. In the initialization operation, the reset switch can be maintained in a conducting state to continue with the reset, at least at that time, as the switching element is in a conducting state. The time when El is UNT switch is in a conducting state when the initialization operation, may be shorter than the time when the switching element is in a conducting state when the operation of the image output described below. In addition, the switching elements on multiple lines can be operated simultaneously in the initialization operation. In such cases, you can reduce the time required to complete the initialization operation to quickly stabilize the changing characteristics of the FPD 104. Operation K1 initialization in the first embodiment, is performed for the period having the same duration as the period of operation of the output image, included in the operation fluoroscopy, accompanying the operation of idling.

Figs is a timing chart illustrating an example of operation of the device imaging during the period B-B', Figa. After the idling operation is executed to install the unit 101 for detecting a state in which you can perform the image capture device 100 of the imaging performs the operation of fluoroscopy, in which the FPD 104 is scanned in the first field of A scan, in response to the control signal from the control computer 108. The operation of the x-ray corresponds to the first operation image capture. The period during which the device 100 imaging performs the operation x-ray, called the Xia period fluoroscopy. During radiography device 100 imaging performs the operation W1 accumulation performed for a period corresponding to the time of irradiation to induce conversion element 201 to generate an electric charge in response to the emitted radiation, and the operation X1 output image in which the image data are displayed on the basis of the electric charge generated by the operation W1 accumulation. As shown in Figs, in the operation of the image output by the first option implementation unit 106, the control signal D-CLK control corresponding to the number of rows corresponding to the second scanning area, the circuit 102 excitation signal OE control signal DIO control in the Lo state. Accordingly, the voltage Vcom of the conductivity is not supplied from the circuit 102 excitation line G1 and G2 excitation and, thus, the first and second rows corresponding to the second scanning area, not scanned. Then the integrating capacitor and the signal line are reset, and the voltage Vcom of the conductivity is applied from the circuit 102 excitation line G3 excitation setup items switch from T31 on T3m in the third line in the conducting state.

As a result, an electrical signal based on electric charge generated in the conversion element is Oh with S31 S3m by the third line, served on each signal line. Each of the electric signals output in parallel via the respective signal lines, increases in the integrating amplifier 203 and a variable amplifier 204 in each amplifier circuit 207. Amplified electric signals are held in parallel circuits 205 sampling and storing in the respective amplifying circuits 207. Circuit 205 sampling and storage are activated in response to the signal SH management. After the electrical signals recorded, the integrating capacitors and the signal line are reset. After a reset voltage Vcom conductivity is applied to the line G4 excitation in the fourth line as the third line to set the switching elements with T41 on T4m the fourth line in the conducting state.

During the period in which the switching elements with T41 on T4m the fourth line is set to the conducting state, the multiplexer 208 sequentially outputs the electrical signals held in the schemes 205 sampling and storage. In the electric signals read in parallel from the pixels in the third line, is converted into a serial image signal, and the serial image signal is displayed. Analog-to-digital Converter 210 converts the image signal into image data corresponding to one line, which displays the image data, resulting from the conversion. Performing the above operations for each row from the third row on the n-th line makes the image data corresponding to one frame, output from the device 100 imaging.

Additionally, in the first embodiment, the device 100 imaging performs the operation W1 accumulation, which occurs during the period having the same duration as the period of operation W1 accumulation to induce conversion element 201 to generate an electric charge in the dark state in which the irradiation is not performed, and the operation F1 of the output of the readout image, in which the dark image is displayed based on the electric charge generated during the operation W1 accumulation.

In operation F1 of the output of the readout image operation similar to the operation X1 output image is performed in the device 100 imaging. Dwell time is the time resulting from adding a time when the accumulation operation, the time resulting from subtracting the time when each switching element is in a conducting state, from the time when the operation of the image output. The time when each switching element is in a conducting state, called the camping scan time. The time when one set of operations of the image capture, includes the accumulation operation, the output operation of the image, the accumulation operation and the output operation of the readout image is called a frame time, and the reciprocal of the time frame is called the frame rate. Although the pixels in the first and second lines are not scanned in the first embodiment, the present invention is not limited to these scanning conditions. For example, all the second pixels corresponding to the pixels in the first and second rows can be scanned simultaneously or the second pixels may be scanned during the scanning period, which is shorter than the first pixels in the first scan area. In other words, the scanning can be performed so that the normal operation of the image capturing is not performed in relation to the second pixel during the first operation of the image capture. Although the pixels in the second scan area is scanned one after the other during the operation K1 initialization Figv, the present invention is not limited to these terms of scanning, and the scanning can be performed as the operation X1 output image.

In response to the flow control signal for prompting device 100 imaging to perform a switching operation from the host computer is and 108 in the device 100 imaging, along with the command to toggle the scan area in the period fluoroscopy, the device 100 imaging performs the switching operation. More precisely, the block 106, the control signals of the control circuit 102 excitation and circuit 103 is read in response to the control signal from the control computer 108, to encourage FPD 104 to perform the switching operation. The period when the FPD 104 performs the switching operation, is called the period of the operation switch. The switching operation will be described in detail below with reference to Fig. 5A-5E.

Fig.4D is a timing chart illustrating an example of operation of the device imaging during C-C' Figa. After the operation of the switching device 100 imaging performs an operation pictures (capture still images), in which the FPD 104 is irradiated with radiation in the second region B of the scan, greater than the first area A scan. Surgery pictures corresponds to the second operation image capture. The period for which the device 100 imaging performs surgery pictures, is called the period pictures. During the period pictures of the device 100 imaging performs the operation W2 accumulation performed for a period corresponding to the time of irradiation to induce transformative e is emant to generate an electric charge in response to the emitted radiation, and operation X2 output image in which the image data are displayed on the basis of the electric charge generated by the operation W2 accumulation. As shown in Fig.4D, although the operation W2 accumulation in the first embodiment, similar operations W1 accumulation operation W2 accumulation differs from the operation W1 accumulation, as the period of operation W2 accumulation is longer than the operation W1 accumulation. In contrast, although the operation X2 output image such operations X1 output image except that the first and second rows are scanned in the same way as the third line and subsequent lines, the operation X2 output image differs from the operation X1 output image, since the operation period X2 of the output image is longer than the operation X1 output image. However, the operation W2 accumulation can be performed in a period having the same duration as the period of operation W1 accumulation, and the operation X2 output image can be performed in a period having the same duration as the period of the operation X1 output image.

In addition, in the first embodiment, the device 100 imaging performs the operation W2 accumulation performed for the period having the same duration as the period of operation W2 accumulation before surgery X2 output shows the I, to force conversion element to generate an electric charge in a dark state in which radiation is not emitted, and the operation of the F2 output of the readout image, in which the dark image is displayed based on the electric charge generated by the operation W2 accumulation. In the operation of the F2 output of the readout image, the operation similar to the operation X2 output image is performed in the device 100 imaging. In addition, in the first embodiment, the device 100 imaging performs the operation K2 initialization before each operation W2 accumulation. Although the operation K2 initialization such operations K1 initialization described above, the operation K2 initialization differs from the operation K1 initialization, since the period of operation K2 initialization is longer than the operation K1 initialization. However, the operation K2 initialization can be performed in a period having the same duration as the period of operation K1 initialization. Operation K2 initialization is performed separately from the operation switch, described below.

Next will be described how there is a diversity level. The inventor has found that the output signal of the readout period of the flat panel detector depends on the history of scanning pixels, more accurately, depends on led the ranks of integration periods of time savings, from how the bias voltage was applied to the conversion element in the flat panel detector. The operation of the image capture is performed in the first scanning area when the first operation image capture in the first embodiment. Accordingly, the operation of image capture is executed multiple times in respect of the first pixels included in the first region A scan, and components of the output signal of the readout period, accumulated during the operation of the accumulation, not fully displayed in each operation o, and remain in pixels. Components remaining in the pixels that correspond to the history of scanning pixels.

In contrast, the normal operation of the image capturing is not performed in relation to the second pixels, which are not included in the first scan area, but included in the second scan area, when the first operation image capture. For example, this problem occurs because the accumulation operation is continuously performed for the second pixel, all the second pixels are scanned at one time, or the output operation of the second pixels is performed in the scanning period shorter than the first pixels. In such cases, the accumulation time of the first pixel is different from the second pixels. For example, when the output operation of the second pixels is performed is recorded in the scan period, shorter than the first pixels, the value of the integration periods of accumulation during the first operation of the image capturing for the first pixel becomes smaller than the second pixel. As a result, there occurs a difference between the output signal of the readout period of the first field scanning and the output signal of the readout period of the second scanning area, and the difference of the output signal of the readout period is displayed as difference of level. In particular, the difference of the output signal of the readout period between the first scan and the second scan area increases with period x-ray and, thus, the level difference becomes more obvious. As described above, the output signal of the readout period of the flat panel detector depends on the integration periods of accumulation, which is the background scan pixels. Therefore, the inventor has found that the difference of the output signal of the readout period occurs between areas that are subjected to scanning with image capture in the flat panel detector, and areas that are not subjected to scanning with image capture in the flat panel detector to cause the difference in level, which is an artifact of the image caused by the scanning area./p>

An exemplary operation of the switch according to the first variant of implementation will be further described with reference to Fig. 5A-5E. With reference to Five, the horizontal axis represents the time elapsed after the start of the operation of the image capture performed after modified radiation field, and the vertical axis represents the magnitude of the differences of level, which is the difference between the output from the pixels included in the first region A scan, and output from the pixels included in the second region B of the scan. The output of the pixel obtained in the dark condition, used as the output pixel data on File.

In operation, switch on the modalities for the implementation of the present invention, the block 106 management takes control signal to switch the scan area, and the FPD 104 performs the initialization operation, at least once in response to the control signal. As shown in Figa, it was found that the magnitude of the difference of level is reduced when the initializing operation is performed by switching the scanning area, as compared with a case in which the initialization operation is not performed. It was also found that the magnitude of the differences of level are further reduced by repeated execution of the initialization operation. The initializing operation can be performed the Dean once or many times to prevent the deterioration of image caused by the difference in level, which may occur in a captured image by switching the scanning area.

In an exemplary operation of the switch shown in Figa, the FPD 104 performs a few operations K2 initialization and operation W2 accumulation during surgery pictures, performed after the change of the radiation field described above with reference to Figa and 4D, once or many times. In other words, the FPD 104 performs a pair consisting of the operation K2 initialization and operation W2 accumulation corresponding to the operation X2 output image and operations of the F2 output of the readout image during surgery pictures, performed after the scanning area is switched once or many times. The switching operation can be performed in accordance with the operation included in the number of operations performed before the operation of the image output part of the operation of the image capture to be performed after switching, to stabilize the characteristics of the Converter element in the operation W2 accumulation operation of the image capture and, thus, get an excellent image data having the reduced size of the artifact image. However, since an electric charge is generated in the conversion element even in dark condition during the operation of the accumulation, the above method was the AET obstacle rapid stabilization of the characteristics of the Converter element. More precisely, when the initializing operation is executed multiple times, the time required for the switching operation may be increased to increase the time before start image capture, as has been switched to the scan area.

In an exemplary operation of the switch shown in Figv, the FPD 104 performs the operation K1 initialization in operation, idling, pre-operative fluoroscopy before switches the scan area, described above with reference to Figa and 4B, one or many times. Since the switch operation is not performed, the accumulation operation, and operation is performed only K1 initialization with the shortest period among the initialization performed by the device 100 imaging, the time required for the switching operation, is reduced to improve the efficiency of the device. However, when the initializing operation performed when the switch operation is an operation of capturing an image after you set the scan area and runs for a period having a duration different from that of the period of the initialization operation performed when the operation of capturing an image after you set the scan area, the stability characteristics of the Converter cell battery (included) is that on operation of the accumulation operation of the image capture may deteriorate. As a result, can be obtained the image data, which has improved the value of the artifact.

In an exemplary operation of the switch shown in Figs, the FPD 104 performs the operation K2 initialization in surgery pictures, performed after the scanning area is switched once or many times. Since the initializing operation included in the operation image capture after the switch, is used in the operation of the switch, the switching operation is performed with the operation initialization, the respective operations of the image capturing is performed after switching, and thus are excellent in image data having a smaller value of the artifact. In addition, because the accumulation operation is not performed, it is possible to quickly stabilize the characteristics of the Converter element. In particular, it is preferable that as the switch operation, including numerous the initialization operation, the initialization operation in the operation of the image capture to be performed after switching was performed at least once immediately before the operation of the image capture to be performed after switching. In order to stabilize the characteristics of the Converter element for a shorter time, it is preferable that both of the op is the radio K1 and initialization operation K2 initialization was performed, at least one time during the operation of the switch shown in Fig.5D.

As described above, the switching operation can be performed before the operation of the image capture after the scanning area is switched to reduce the artifact (distinction level), which may occur in a captured image, and which depends on the scanning area, thereby preventing a significant reduction in the quality of the image.

Although the PIN photodiode is used in the conversion element 201 in block 101 of the detection in the first embodiment of implementation of the photoelectric Converter, mausismuhkuh metal-insulator-semiconductor (MIS) is used as the conversion element 601 type MIS in block 101' detection according to the second variant of implementation. Although one output switching element provided for one pixel in the first embodiment, the element 603 switching recovery is provided in addition to the output element 602 switching to one pixel in the second embodiment.

Examples of the operation of the imaging system and imaging according to the second variant of implementation of the present invention will be described hereinafter with reference to Fig. 7A-7D. In the second embodiment, as shown in Figa, the operation K1' initialization operation X1' of the output image and the operation F1' input dark image will be executed instead of the operation K1 initialization operation X1 output image and operations of the F1 output of the readout of the image, respectively, on the first version of the implementation shown in Figa. In addition, the operation X2' of the output image and the operation F2' o dark image is the position executed instead of the operation X2 output image and operations of the F2 output of the readout image, accordingly, in the first embodiment of the implementation shown in Figa. Other operations are similar to those in the first embodiment of implementation. A detailed description of such operations in the materials of this application is omitted. The operations that are different from those in the first embodiment of the implementation, will hereinafter be described with reference to Fig. 7B-7D.

Figs is a timing chart illustrating an example of operation of the device imaging during the period B-B', Figa. Fig.7D is a timing chart illustrating an example of operation of the device imaging during C-C' Figa.

Block 101' detection according to the second variant implementation includes an element 603 switching recovery in addition to the output element 602 switching to one pixel. Accordingly, the operation K1' initialization when the idling operation in the second embodiment, shown in Figv, distinct from the operation K1 initialization, in which one conversion element 201 operates on one pixel. In operation K1' recovery voltage Vcom conductivity is supplied from the circuit 102 excitation line G excitation, in order to set the output element 602 switch conductive when standing, and electric charge in the conversion element 601 is output from the output element 602 switching as an electrical signal, as in the first embodiment. Then the voltage Vcom conductivity is supplied from the circuit 102r excitation recovery line Gr excitation restore, to set the element 603 switching recovery in a conductive state. At this time, the voltage Vt recovery is fed from a source 107c power recovery. As a result, the bias |Vs-Vt| is applied to the conversion element 601 to remove the electric charge remaining in the conversion element 601, thereby restoring conversion element 601. Then, the integrating capacitor and the signal line are reset, the output element 602 switch is again set to the conducting state, and the initial bias |Vs-Vref| is applied to the conversion element 601 to initialize the conversion element 601. The consistent implementation of the above steps in blocks of rows successfully performs the operation K1' initialization. As described above, since the other operations are similar to those in the first embodiment implementation, the detailed description of these operations in the materials of this application is omitted.

The difference between the operation X1' output image with the erali fluoroscopy in the second embodiment, shown in Figs, and operation X1 output image, and the difference between the operation F1' o dark image when performing fluoroscopy in the second embodiment, shown in Figs, and the F1 output of the readout image similar to the difference between the operation K1' initialization and operation K1 initialization described above. Since the other operations are similar to those in the first embodiment implementation, the detailed description of these operations in the materials of this application is omitted. Although the pixels in the second scan area is scanned one after the other during the operation K1' initialization Figv, the present invention is not limited to scanning, and the operation K1' initialization can be done in some way, similar to that of the operation X1' output image.

In operation X2' of the output image and the operation F2' o dark images during surgery pictures on the second version of the implementation shown in Fig.7D, the voltage Vcom conductivity is supplied from the circuit 102 excitation line G excitation, in order to set the output element 602 switching to the conducting state, as in the first embodiment. As a result, electric charge in the conversion element 601 is output from the output element 602 switching as an electrical signal in units of lines, and data, and is deduced from the considerations applying device imaging through the circuit 103 is read. Then the voltage Vcom conductivity is supplied from the circuit 102r excitation recovery line Gr excitation restore, to set the element 603 switching recovery in a conductive state. At this time, the voltage Vt recovery is fed from a source 107c power recovery. As a result, the bias |Vs-Vt| is applied to the conversion element 601 to remove the electric charge remaining in the conversion element 601, thereby restoring conversion element 601. Then the integrating capacitor and the signal line are reset, the output element 602 switch is again set to the conducting state, and the initial bias |Vs-Vref| is applied to the conversion element 601 to initialize the conversion element 601. The consistent implementation of the above steps in blocks of rows successfully performs the operation X2' of the output image or the operation F2' o dark image. Although the operation X2' of the output image is different from the operation X1' of the output image, as the period of operation x2' of the output image is different from that of the operation X1' of the image output operation X2' of the output image can be performed in a period having the same duration as the period of the operation X1' output image.

Exemplary operations pereklucheniya second variant implementation of the present invention will hereinafter be described with reference to Fig. 8A-8C.

In an exemplary operation of the switch shown in Figa, the FPD 104 performs the operation K2' initialization, such transactions K1' initialization, one or many times over a period having the same duration as the period of operation X2' of the output image and the operation F2' o dark images during surgery pictures. In other words, the FPD 104 performs the operation K2' initialization, the corresponding operation X2' of the output image and the operation F2' o dark images during surgery pictures, performed after the scanning area is switched once or many times. In operation K2' initialization, switching operation is performed with the operation initialization, the respective operations of the image capturing is performed after switching and, thus, get an excellent image data having the reduced size of the artifact image. Because the accumulation operation is not performed, it is possible to quickly stabilize the characteristics of the Converter element. In particular, as an operation switch, which includes numerous, the initialization operation, the initialization operation corresponding to the operation of the image capture to be performed after the switching is preferably performed at least once prior to surgery capturing the image, post-switch.

In an exemplary operation of the switch shown in Figv, FPD 104 primarily performs the operation R recovery, described below, at least once. Then, the FPD 104 performs the operation K2' initialization, the corresponding operation X2' of the output image and the operation F2' o dark images during surgery pictures, performed after the scanning area is switched once or many times. When this switchover operation, in addition to the advantages of the operation of the switch shown in Figa, you can further reduce the difference in level as the electric charge remaining in the transformative element, is removed by the operation R recovery. The restore operation will be described hereinafter with reference to Figs. Figs is a timing chart illustrating an example of operation of the device imaging during the period D-D' on Figv.

To restore operation, shown in Figs, the circuit 102 excitation do not apply voltage Vcom conductivity to the output element of the switch 602, and the output element 602 switch is held in the nonconductive state. In this state, the circuit 102r excitation recovery applies the voltage Vcom conductivity to the element 603 switching recovery in blocks of rows to set the element 603 PE is clucene recovery in a conductive state. As a result, the bias |Vs-Vt| is applied to the conversion element 601 to remove the electric charge remaining in the conversion element 601, thereby restoring conversion element 601. The consistent implementation of the above steps in blocks of rows successfully performs the operation R recovery.

After the operation R recovery of the integrating capacitor and the signal line reset voltage Vcom conductivity is applied from the circuit 102 excitation to the G line excitation, in order to set the output element 602 switching to the conducting state, and the electric charge in the conversion element 601 is output from the output element 602 switching as an electrical signal. Then the voltage Vcom conductivity is applied from the circuit 102r excitation restore to the line Gr excitation restore, to set the element 603 switching recovery in a conductive state. At this time, the voltage Vt recovery is applied from a source 107c power recovery. As a result, the bias |Vs-Vt| is applied to the conversion element 601 to remove the electric charge remaining in the conversion element 601, thereby again restoring the conversion element 601. Then integrating capacitor and signalname reset output element 602 switch is again set to the conducting state, and the initial bias |Vs-Vref| is applied to the conversion element 601 to initialize the conversion element 601. The consistent implementation of the above steps in blocks of rows successfully performs the operation K2' initialization.

Moreover, in the second embodiment, the second operation image capture may include initialization operation, as in the first embodiment.

Moreover, in the second embodiment, the switching operation can be performed before the operation of the image capture after the scanning area is switched to reduce the artifact (distinction level), which may occur in a captured image, and which depends on the scanning area, thereby preventing a significant reduction in the quality of the image.

SUBSTANCE: invention relates to stereoscopic reproduction. In performing stereoscopic view, shift information memory (21) stores, as a number of pixel lengths, an offset indicating how far in a right direction or a left direction to move coordinates of pixels to realise stereoscopic view. When realising stereoscopic view, a plane shift engine (20) moves the coordinates of image data in a graphics plane in the right direction or left direction by the number of pixel lengths indicated by the offset. When a scale of video data targeted for stereoscopic view is changed by a basic graphics plane (15), a shift distance of pixel coordinates by the plane shift engine (20) is based on a number of pixel lengths obtained by multiplying the offset by a changed scaling factor in the horizontal direction.

EFFECT: preserving the depth balance between the video and the subtitle even after GUI processing with scaling is performed, and preventing the occurrence of unnatural change of the stereoscopic structure.
