Abstract
A PET apparatus () includes a detecting section (). Each cylindrical detector () of the detecting section () has a plurality of block detectors (to) arranged on the same circumference on a place perpendicular to a central axis (CAX) in the form of a ring. Each block detector () is a two-dimensional position detector which detects the two-dimensional incident position of a photon incident on a light-receiving surface. Each slice collimator () extends to a rear portion of a corresponding one of cylindrical detectors () through the space between adjacent cylindrical detectors () and () and is integrally fixed by a holding plate () at the rear portion.
