Abstract
A radiation imaging system is configured by a collimatorA including a detectorwith a discrete detection pixel corresponding with a pixel and a plurality of radiation passagesand looks into a plurality of detectorsthrough one radiation passageto set a step width of rotation around a rotation center axis Xonly for an angle θp made by lines provided by connecting a center detectorof the radiation passageand the adjacent two detectors. 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 (−θp, 0, +θp) in the circumferential direction of the rotation center axis Xand thereby one plane projection image is obtained.
