Document Type and Number:
WIPO Patent Application WO/2012/093526
Kind Code:
A1
Abstract:
Provided is a radiation detector which is prevented from deterioration in the detection efficiency, while having good temporal characteristics. A radiation detector (1) for detecting radiation, which is provided with: a scintillator array (10) that comprises a plurality of scintillator cells (11); a photodetector array (20) that comprises a plurality of photodetectors (21); and a photodetector array (30) that comprises a plurality of photodetectors (31). The plurality of photodetectors (21) and the plurality of photodetectors (31) are photodetectors that are capable of transmitting gamma rays (G1, G2). Each scintillator cell (11) is divided into a plurality of light emitting regions (11a, 11b) by a reflective region (12), and the reflective region (12) extends between an incident surface (10a) and a back surface (10b) along a surface (SP) that is inclined to the incident surface (10a) and to the back surface (10b).
