MULTI-LAYER SCINTILLATION DETECTOR WITH 3D POSITIONING CAPABILITY FOR PINHOLE GAMMA CAMERA

摘要

PURPOSE: A multilayer flat type detector and a 3D location detecting method for measuring gamma-ray image are provided to use for a gamma-ray image detector essential for environment monitoring and nuclear medicine imaging. CONSTITUTION: A multilayer flat type detector for measuring gamma-ray image comprises a first multilayer block type flash crystal(10), and a 2-dimensional photo sensor(30). The first multilayer block type flash crystal comprises a 2-dimensional block type flash crystal(11) and 2-dimensional block type optical glass layers(12,13). The 2-dimensional photo sensor senses an optical signal. The first multilayer block type flash crystal and 2-dimensional photo sensor are optically combined. A detector module sets up a 3D index table using the first multilayer block type flash crystal. The multilayer block type flash crystal is composed of a flash crystal which can obtain experimental location information on 3D gamma-ray reaction.
