摘要： A radiographic image capture system includes a radiation detector, a radiation source, a generator, and a controller. The radiation detector includes plural pixels that generate electrical charges upon irradiation with radiation and that accumulate the electrical charges. The radiation source irradiates radiation onto the radiation detector. The generator reads the respective electrical charges accumulated in each of the pixels as electrical signals and generates image data. The controller causes the generator to read the electrical charges accumulated in each of the pixels at a specific frame rate in cases where continuous fluoroscopic imaging is performed, and, in a case in which a specific condition is satisfied, causes the radiation source to reduce the radiation amount being irradiated and causes the generator to perform thinned reading to read out the pixels one section at a time while extending the reading cycle of the electrical charges for each pixel.

摘要： A radiographic image capturing system includes a radiographic image capturing device, a radiation irradiating device, and a control device. The radiographic image capturing device is capable of performing fluoroscopic imaging, and carries out capturing of radiographic images continuously. The radiation irradiating device performs continuous irradiation or pulse irradiation with respect to the radiographic image capturing device at a time of fluoroscopic imaging. The control device has a controller that affects control such that, in a case in which a frame rate of fluoroscopic imaging is low, the radiation irradiating device performs fluoroscopic imaging by the continuous irradiation with respect to the radiographic image capturing device.

摘要： A radiographic image capturing apparatus includes a photodetector substrate, a scintillator, a switching filter, and a resetting light source, 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 allows resetting light to be applied to the photodetector substrate through the scintillator, whereas, 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.
