RADIOLOGICAL IMAGE DETECTION APPARATUS AND METHOD FOR MANUFACTURING THE SAME |
摘要 |
A radiological image detection apparatus includes: a scintillator which is formed out of a group of columnar crystals in which crystals of a fluorescent material emitting fluorescence when irradiated with radiation have grown into columnar shapes; and a photodetector which detects the fluorescence emitted by the scintillator as an electric signal. Activator density in the scintillator varies between high density and low density repeatedly in a radiation travelling direction in at least a part of the scintillator. The activator density in each of front end portions and base end portions of the columnar crystals is lower than the high density.
