Abstract
A PET apparatus includes a detecting unit; slice septa for transmitting therethrough flying photons nearly perpendicular to the center axis; a slice septa position determining section for determining whether or not the slice septa exist in the measurement space side of at least one of the pair of photon detectors; a two-dimensional projection image storage section for storing coincidence-counting information of the photon pair obtained by the pair of photon detectors; a three-dimensional projection data storage section for storing coincidence counting information obtained by the pair of photon detectors; and an image reconstructing section for reconstruction an image indicative of a spatial distribution of a frequency at which photon pairs are emitted in the measurement space.
