    Abstract: A radiation image photographing apparatus includes a hardware processor that, at a time of a radiation image photographing process, repeats a reset process of releasing a charge from a radiation detecting element by sequentially applying an on-voltage from a scan driver to scan lines, until a radiation irradiation is started, provides a predetermined waiting time to cause all switches to wait in an off-state after the reset process and before the next reset process, transitions to a charge accumulation mode of accumulating the charge in the radiation detecting element by applying an off-voltage to all scan lines, in response to radiation irradiation start, and transitions to a reading mode of releasing the charge from the radiation detecting element by applying the on-voltage to the scan lines, and performing an image data reading process by converting the released charge into image data, when a predetermined accumulation time has elapsed.

    Abstract: A non-transitory computer-readable storage medium stores a program that causes a computer to perform an obtaining process, an analyzing process, and an extracting process. In the obtaining process, the computer obtains a radiographic moving image showing a motion of a specific part of an examinee. In the analyzing process, the computer analyzes the radiographic moving image obtained in the obtaining process. In the extracting process, the computer extracts, among frames constituting the radiographic moving image, a specific frame that visibly shows a detection target in the specific part, based on a result of analyzing a dynamic state of the specific part in the analyzing process.

    Abstract: A radiographic image capturing system includes the following. A radiographic image capturing apparatus includes a two-dimensional array of radiation detecting elements and a control circuit which controls reading of image data from each of the radiation detecting elements based on a predetermined capturing sequence. An image processor has first gain data to correct gains of the radiation detecting elements, and generates a radiographic image based on the corrected image data. The control circuit of the radiographic image capturing apparatus is capable of varying at least one of a reverse bias voltage and a signal line voltage to be applied to the corresponding signal line. The control circuit reads a signal value from each of the radiation detecting elements, creates second gain data based on the read signal value, and corrects the radiographic image with the first gain data and the second gain data.
