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.

A timing to acquire a still image signal is controlled such that a sum (Tst+Trd) of a storage period Tst and a readout period Trd for the still image signal is an integral multiple (Ts+Tr=Tck×n, where n is an integer of 2 or greater) of a cycle Tck of a moving image capturing mode, when a detector controller acquires the still image signal while acquiring a moving image signal from a radiation detector during the cycle Tck (Ts+Tr) of the moving image capturing mode.

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.

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.

A radiation image capturing device has: a radiation image capturing section that is adapted to image capturing in a selected operation mode, an image processing section, a power supply section that supplies electric power for driving to the radiation image capturing section, a connection portion that electrically connects to at least one of a power supply device or an image processing device, and a control section. The control section effects control such that, in a case in which an operation mode that generates a predetermined generated heat amount or more is selected and the power supply device is connected to the connection portion, the power supply device is used instead of the power supply section, and, in a case in which an operation mode that generates a predetermined generated heat amount or more is selected and the image processing device is connected to the connection portion, the image processing device is used instead of the image processing section.

A radiographic image capture device includes a radiation detector, an application section and a controller. The radiation detector includes plural detection pixels that detect a radiation application state and plural imaging pixels that capture a radiographic image. The application section applies a bias voltage to each of the plural detection pixels and to each of the plural imaging pixels. The controller effects control such that, if the radiation application amount detected by the detection pixels is equal to or greater than a first threshold value during a first state in which the bias voltage is applied to the plural detection pixels, the application section is caused to transition to a second state in which the bias voltage applied to the detection pixels is reduced.
