RADIATION IMAGING SYSTEM AND NUCLEAR MEDICINE DIAGNOSIS INSTRUMENT THEREFOR

摘要

A radiation imaging system is configured by a collimator 30A including a detector 21 with a discrete detection pixel corresponding with a pixel and a plurality of radiation passages 31 and looks into a plurality of detectors 21 through one radiation passage 31 to set a step width of rotation around a rotation center axis X1 only for an angle thetap made by lines provided by connecting a center detector 21 of the radiation passage 31 and the adjacent two detectors 21. In the case of generating a flat plane projection image for one direction, radio-graphing is carried out on a projection image in a plurality of predetermined angle positions (-thetap, 0, +thetap) in the circumferential direction of the rotation center axis X1 and thereby one plane projection image is obtained.
