Abstract: A determination section of an FPD checks external information against a determination table and determines whether detection of a rise of X-ray pulses is allowed based on an output voltage from a short-circuited pixel. The FPD detects X-ray images. The external information is transmitted from an imaging control device. The X-ray pulses are sequentially generated by an X-ray generating apparatus. A controller selects a pulse irradiation mode in a case where the detection of the rise of the X-ray pulse is allowed. If not, a successive irradiation mode is selected. In the pulse irradiation mode, the rise and the fall of the X-ray pulse are detected and timing of storage operation is synchronized with the detected timing of the rise. In the successive irradiation mode, the storage operation is performed at predetermined time intervals without the detection of the rise and the fall of the X-ray pulse.

Abstract: An X-ray image detecting device has an FPD having a matrix of pixels each for accumulating signal charge in accordance with an X-ray irradiation amount. An imaging area of the FPD is partitioned into a plurality of divided sections A to I. Each of the divided sections A to I has a short pixel for detecting X-ray irradiation. In a synchronization control for controlling the FPD in synchronization with detection of a start of X-ray emission from an X-ray source, a control unit for controlling the X-ray image detecting device uses all the divided sections A to I. In an automatic exposure control for stopping the X-ray emission from the X-ray source by detecting a total X-ray irradiation amount, the control unit uses part of the divided sections, e.g. the short pixels of the divided sections that are judged to be opposed to an object in the synchronization control.

Abstract: An X-ray imaging apparatus includes an FPD and short-circuited pixels. The FPD has pixels arranged in arrays for detecting an X-ray image. The short-circuited pixels detect a radiation dose of X-rays in the FPD. The X-ray imaging apparatus is changed over between first and second operating modes. The first operating mode is selected in case of combining with an X-ray generating apparatus with communication compatibility, and performs an exposure control for controlling a total radiation dose according to a detection signal from the short-circuited pixels. The second operating mode is selected in case of combining with an X-ray generating apparatus with communication incompatibility, and performs control of start synchronization for synchronizing operation of the FPD with the emission start of X-rays according to a detection signal from the short-circuited pixels.
