Abstract: A radiography system includes an image former, a first determiner, and an operation controller. The image former performs serial radiography of repeatedly generating a frame that constitutes a video. The first determiner determines whether a next test action is the serial radiography. The operation controller makes the image former begin turning a switch element on/off in a same manner as a manner in the serial radiography before start of the next test action in a case where the first determiner determines that the next test action is the serial radiography.

Abstract: A radiation image capturing apparatus includes scan lines of 1st to nth lines, scan driving units, a controller, an OE signal line and a CPV signal line. The OE signal line is to input OE signal by which an ON voltage is applied to a scan line. The CPV signal line is to input CPV signal by which the scan line, to which the ON voltage is applied by the input of the OE signal, is shifted to a next scan line. To the scan driving units, the controller inputs the CPV signal to sequentially shift the scan line from the 1st line to the nth line, and inputs the OE signal to apply the ON voltage only when the scan line is a scan line of an effective pixel region from which image data is read.

Abstract: A radiation image capturing system includes the following. A radiation irradiating apparatus irradiates the radiation image capturing apparatus according to control by a generator. A control device transmits an external synchronizing signal to the radiation image capturing apparatus, transmits an irradiating request signal to the generator, and synchronizes the radiation image capturing apparatus with the radiation irradiating apparatus. When the external synchronizing signal is received, the radiation image capturing apparatus switches the control mode. After the control mode is switched, the radiation image capturing apparatus starts a readout process of the image data at a timing delayed a predetermined amount of time from a timing that the external synchronizing signal is received. The control device transmits the irradiating request signal to the generator at a timing delayed a predetermined amount of time from a timing that the irradiating request signal should be transmitted to the generator.

Abstract: A radiographic image capturing apparatus includes: scanning and signal lines; a two-dimensional array of detecting elements defining a detecting part; a control unit that reads image data from all detecting elements in a reading area of the detecting part by repeating a cycle of a readout process at N-line intervals, wherein the scanning line subjected to the readout process is shifted every cycle, where N is an integral number of at least 1; and a communication unit for external communication. The control unit detects a radiation emission start of a radiation irradiating apparatus, and if the readout process starts with an N+1th or any subsequent scanning line and then starts with any of first to N+1th scanning lines in a certain cycle, the control unit transfers the image data read in the certain cycle as preview image data substantially concurrently with the readout process.

Abstract: A radiation image capturing apparatus includes a control unit. The control unit alternately carries out (a) a leak data readout process to read out electric charges leaking from radiation detection elements via switch elements set in an OFF state as leak data and (b) a reset process of the radiation detection elements. When a value of the leak data read out in the leak data readout process is equal to or greater than a threshold, the control unit repeats the leak data readout process, skipping the reset process. The control unit detects start of irradiation of the radiation image capturing apparatus when a value of the leak data read out in the repeated readout process is again equal to or greater than the threshold, and does not detect start of the irradiation when the value is smaller than the threshold.
