RADIATION TOMOGRAPHY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a radiation tomography method and device shortened in scanning time equivalently. SOLUTION: Data about the projection of a subject produced by a plurality of radiation beams are sequentially measured in a plurality of viewing directions around the subject, and interpolated projection data are calculated by performing weighting computations so that opposite view data are weighted chiefly on the desired time phase. Tomograms are produced in accordance with the interpolated projection data and tomography approximating a still image of a target organ in the desired time phase is performed.
