摘要： A radiographic imaging device includes: a radiation detector including plural pixels, each including a sensor portion and a switching element; a detection unit that detects a radiation irradiation start if an electrical signal caused by charges generated in the sensor portion satisfies a specific irradiation detection condition, and/or if an electrical signal caused by charges generated in a radiation sensor portion that is different from the sensor portion satisfies a specific irradiation detection condition; and a control unit that determines whether or not noise caused by external disturbance has occurred after the detection unit has detected the radiation irradiation start, and if the noise has occurred, that stops a current operation of the radiation detector, and causes the detection unit to perform detection.

摘要： Radiation images with different resolutions may be captured using a general-purpose driver configured with a shift register group in a single system. Each shift register is connected to a first gate line or a second gate line via a connection terminal in accordance with wiring of a radiation detector. Under the control of an FPGA, in a case of low resolution imaging, a panel control section outputs OE signals that disable the output of on signals from the shift registers to the first gate lines in accordance with CPK signals. In a case of high resolution imaging, the panel control section outputs OE signals that disable the output of on signals from the shift registers to the second gate lines. In both cases, an on signal outputted from a shift register is inputted to a succeeding shift register.

摘要： The present invention provides a radiographic image detector that may maintain even resolution in 6 directions before and after 3-pixel binning process. Namely, out of plural pixels with hexagonal shaped pixel regions in a radiation detector, for plural pixel groups respectively configured from 3 pixels, 3 pixels worth of charges in the radiation detector are read together, the charge signals of these 3 pixels combined, and integrated in sequence with a charge amplifier. For specific pixel groups, out of 3 pixels configuring the specific pixel groups, the charge signals of 2 pixels worth, and the charge signal of the remaining 1 pixel worth are summed with the same charge amplifier using shifted integration timings. 3-pixel binning is thereby performed.

摘要： The present invention provides a radiographic imaging device, radiographic imaging system, a program for controlling the radiographic imaging device, and a method for controlling the radiographic imaging device that may accurately detect start of irradiation of radiation even noises are generated by interference or the like. When radiation is irradiated, electric signals outputted from radiation detection pixels in charge accumulation period are detected by signal detection circuit during detection period. Control section determines whether time variation of the electric signals feature pre-specified characteristics of noise. If not, the start of the irradiation of radiation has been properly detected, the charge accumulation period continues, and radiographic image is imaged. However, if the electric signals feature the pre-specified characteristics, it is determined that the start of the irradiation of radiation has been misdetected, the charge accumulation period is stopped, and is switched to radiation detection period.

Detection of radiation is carried out on the basis of a difference between an electric signal flowing through the first signal line and an electric signal flowing through the second signal line, or a difference between values of digital data obtained by digitally converting an electric signal flowing through the first signal line and an electric signal flowing through the second signal line, respectively.
