Abstract
A radiological image detection apparatus, includes: two scintillators that convert irradiated radiation into lights; and a photodetector arranged between two scintillators, that detects the lights converted by two scintillators as an electric signal; in which: an activator density in the scintillator arranged at least on a radiation incident side out of two scintillators in vicinity of the photodetector is relatively higher than an activator density in the scintillator on an opposite side to a photodetector side.
Claims19
A radiological image detection apparatus, comprising:
- two scintillators configured to convert irradiated radiation into lights;
- and
- a photodetector arranged between two scintillators configured to detect the lights converted by the two scintillators as an electric signal;
- wherein:
- an activator density in the scintillator arranged at least on a radiation incident side out of two scintillators in vicinity of the photodetector is relatively higher than an activator density in the scintillator on an opposite side to a photodetector side and the activator density in each of the two scintillators changes in a width direction in the scintillators.
A radiological image detection apparatus, comprising:
- two scintillators configured to convert irradiated radiation into lights;
- and
- a photodetector arranged between two scintillators configured to detect the lights converted by two scintillators as an electric signal;
- wherein:
- an activator density in at least one scintillator out of two scintillators in vicinity of the photodetector is changed repeatedly between a high density and a low density in a radiation traveling direction and the activator density in each of the two scintillators changes in a width direction in the scintillators.
