Radiographic image capturing apparatus

A radiographic image capturing apparatus comprising:

• a scintillator for converting radiation into fluorescence;
• a photodetector substrate for converting the fluorescence into electric signals;
• a resetting light source for applying resetting light to the photodetector substrate;
• and
• a switching filter, which is selectively permeable and impermeable to the resetting light,
• wherein the photodetector substrate, the scintillator, the switching filter, and the resetting light source are arranged in this order, and
• if the switching filter is made permeable to the resetting light, the switching filter allows the resetting light to be applied to the photodetector substrate through the scintillator, and if the switching filter is made impermeable to the resetting light, the switching filter reflects at least the fluorescence toward the photodetector substrate.
