ABSTRACT:
A radiation tomography method and apparatus which can image at a time a plurality of tomographic images which differ in slice thickness is implemented. A projection image of a subject projected by a radiation beam 40 having an extent and a thickness is divided in the thickness direction of the radiation beam by detector arrays 240 and 242, and their respective projection data are measured in a plurality of view directions. Then, the tomographic images are produced respectively based on the projection data for each of the divided projection images and the projection data for all of the divided projection images.
