Abstract
A radiation detection device has: a scintillator for converting radiation into fluorescence; a photoelectric conversion unit for converting the fluorescence into an electric signal; and a reset light source unit for exposing reset light to the photoelectric conversion unit. A system control unit has an optical reset disabling unit for, based on a reset disabling instruction, disabling the exposure of the reset light output from the reset light source unit.
Claims29
A radiographic image capturing system comprising:
- a radiographic image capturing apparatus including a radiation applying device having a radiation source and a radiation detecting device for converting radiation emitted from the radiation source and transmitted through a subject into a radiographic image and supplying the radiographic image;
- and
- a system control portion for controlling the radiographic image capturing apparatus to perform a radiographic image capturing process at a preset frame rate;
- wherein the radiation detecting device has a scintillator for converting the radiation into fluorescence, a photoelectric transducing portion for converting the fluorescence into an electric signal, and a resetting light source for irradiating the photoelectric transducing portion with resetting light;
- and
- the system control portion has a light resetting nullifying portion for nullifying application of the resetting light from the resetting light source in response to a resetting nullifying command.
