Abstract
A crystal detector array, particularly for a high resolution radioactivity distribution detection system, with a plurality of crystal assemblies that are disposed in rows and columns and define a sensing array. Each crystal assembly is provided with four sensing heads. Each head is a quadrant of the crystal assembly and is identified by a unique address location in the array. A plurality of detectors are superimposed on the sensing array. Certain ones of the detectors are in registration with one sensing head of four crystal assemblies in adjacent rows and columns. Radioactive events emitted from a subject under diagnosis activate selected ones of the sensing heads. Light signals generated by the activated heads are detected by the detectors and processed to provide a presentation of radioactivity distribution within the subject under diagnosis.
