COLLIMATOR OF SCINTILLATION CAMERA AND DATA COLLECTION METHOD FOR TOMOGRAPHY IMAGE BY USING IT

摘要

PROBLEM TO BE SOLVED: To obtain an image of tomography with a collimator of a scintillation camera which is simple in structure, producible with good accuracy, makes the uniformity of collected data good and has a small number of arch facts. ;SOLUTION: Combined are a collimator base member 18 forming a multitude of parallel slits 23 by arranging vertically a multitude of shielding plates constituted of radiation shield members and formed like a long and thin plate in horizontal direction with specific intervals, a support stage 19 standing up from one plane of the collimator base member 18 nearly vertically to the plane, and radiation shield rods 20 arranged in the direction perpendicular to the longitudinal direction of the parallel slits 23 of the collimator base member 18 supported detachably by the support stage 19. By this, a collimator with a simple structure and capable of accurately producing is provided.;COPYRIGHT: (C)1997,JPO
