摘要： A flat panel detector has pixels for obtaining image signals and detective pixels for detecting the amount of incident x-rays. A signal processing circuit is of a pipeline-type, wherein first and second buffer memories are connected to the output of an A/D converter. In a dose detecting operation, the signal processing circuit repeats primary cycles alternately with secondary cycles of a shorter length than the primary cycles. In the primary cycle, a dose detection signal based on electric charges from the detective pixels is input in the first buffer memory and, simultaneously, a dummy signal is output from the second buffer memory. In secondary cycle, the dose detection signal is output from the first buffer memory and, simultaneously, a second dummy signal is input in the second buffer memory. On the basis of the dose detection signals, a start-of-radiation detector detects the start of x-ray radiation.

摘要： Binning readout reads out electric charge accumulated in pixels to signal lines in blocks of a plurality of adjoining pixel-rows. A correction image generator of a line defect corrector scales up an image size of a reference frame image RP outputted by the binning readout and corrects pixel values of the reference frame image RP, to produce a correction image RPC to be used for correction of a line defect occurring in an X-ray image XP. The scale-up is performed by applying row interpolation processing to the reference frame image RP. The correction of the pixel values is performed by multiplying the reference frame image RP after being subjected to the row interpolation processing by a correction coefficient. An adder adds the correction image RPC to the X-ray image XP, and produces an X-ray image XPC in which the line defect is corrected.

摘要： A radiation detector includes a memory controller and a sleep control unit. The sleep control unit supplies a power supply power to a main control unit and cuts off supply of the power supply power to at least a part other than the main control unit in a first power consumption reduction mode. In addition, the sleep control unit cuts off supply of the power supply power to at least a part of the main control unit and at least a part other than the main control unit in a second power consumption reduction mode. In addition, the memory controller prevents a volatile memory from being deactivated during the second power consumption reduction mode.

摘要： A radiological image-capturing device includes: a first read control section that executes a first read mode in which electric signals stored in a plurality of pixels are read out simultaneously in units of a plurality of rows; and an emission-start determining section that determines that the emission of radiation from a radiation source onto an image-capturing panel has started when the values of the electric signals read by the first read control section have become greater than an arbitrarily settable threshold. If it is determined by the emission-start determining section that the emission of the radiation has started, the first read control section terminates the reading of the electric signals, and thereby brings the image-capturing panel into an exposure state.
