摘要： A radiographic image capturing apparatus includes a resetting light source, a switching filter, a photodetector substrate, and a scintillator, which are arranged successively in this order. If the switching filter is made permeable to resetting light from the resetting light source, the switching filter applies the resetting light to the photodetector substrate. If the switching filter is made impermeable to the resetting light, the switching filter reflects at least a fluorescence, which is converted from radiation by the scintillator, toward the photodetector substrate.

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： Placement of a marker is performed efficiently, when performing a plurality of radiation imaging operations of a subject with different imaging angles. An operator inputs a region of interest within a subject on a bed, via an operating section. The region of interest and a peripheral region thereof are set as an irradiation range, and the marker is placed in the peripheral region. A radiation source control section causes a radiation source to emit radiation toward the subject within the set irradiation range. Radiation which passes through the subject is obtained by a radiation image detector as a radiation image.
