Abstract
A first γ-ray generating in a body, caused by a PET pharmaceutical, and a second γ-ray emitted from a γ-ray source and transmitting through the body are detected with a radiation detector. The emission image information (E image information), E, Eand E, at each of patient motion phases,and, which divided a respiration period, are prepared by using information obtained from the detected first γ-ray. The transmission image information (T image information), T, Tand T, at each of patient motion phases,and, respectively, are prepared, by using information obtained from the detected second γ-ray. Relative displacements, ([F], [F]), are determined by superimposing, on T image information T, other T image information, Tand T. The E image information, E, E, are superimposed on the E image information E, by using this relative displacement.
