摘要： A radiographic image capturing system includes a radiographic image capture device, a radiation irradiation device, and a control device. The radiographic image capture device is capable of wired and wireless communications, and is capable of fluoroscopic imaging in which radiographic images are successively captured at notified synchronization timings or at a predetermined frame rate. The radiation irradiation device irradiates radiation toward the radiographic image capture device during fluoroscopic imaging, with continuous irradiation or pulse irradiation. The control device includes a wireless communication unit, a wired communication unit, and a controller that, if communication with the radiographic image capture device is performed by the wireless communication unit, prohibits fluoroscopic imaging with pulse irradiation in which the synchronization timings are notified to the radiographic image capture device and radiation is irradiated from the radiation irradiation device in pulses matching the notified synchronization timings.

摘要： A radiation image capturing device includes a radiation image capturing unit, a diaphragm unit, and a control unit. The radiation image capturing unit captures a radiation image based on radiation transmitted through a subject. The diaphragm unit has an opening region that is configured to transmit a part of the radiation emitted from a radiation source and an area thereof is changeable, and the diaphragm unit is configured such that a transmission dose of the radiation decreases as a distance from a circumferential part of the opening region increases. The control unit controls the diaphragm unit such that direct rays of the radiation are irradiated onto a predetermined region of the subject.

摘要： An imaging area specifying apparatus that includes a storage component and a specifying component is provided. The storage component stores as correlation information a correlation value correlated with the amount of radiation emitted to each of a plurality of predetermined areas divided from a detection region of a radiation detector that outputs an electric signal indicating a radiological image represented by radiation which is emitted to the detection region for detecting the radiation. The specifying component specifies an imaging area capable of capturing the radiological image of a predetermined size while preventing variations in the amount of radiation emitted to each of the divided areas in the detection region, on the basis of the correlation information stored in the storage component.
