うことを特徴とするポジトロンＥＣＴ装置。 It has a ring-shaped detector array consisting of a large number of radiation detectors arranged in a ring around the subject, and each of the above detectors detects and collects positron annihilation gamma rays emitted from within the subject. A positron ECT device that reconstructs a distribution image of positron-emitting nuclides within a subject by processing the data by a computer, and has a mechanism for reciprocating the ring-shaped detector array in the slice thickness direction. A positron ECT apparatus characterized in that data collection is performed once by repeatedly positioning the ring-shaped detector array at at least two positions in the slice thickness direction alternately.
