SCINTIGRAPHIC DIRECTIONAL DETECTOR

摘要

A scintigraphic directional detector comprises a plurality of detecting elements (10) distinct from each other for simultaneously detecting gamma rays directed in different directions, each detecting element (10) comprising at least one scintillation crystal (11) and a corresponding electronic converter (12) associated with the crystal (1 1) to receive an optical signal from the crystal (1 1) and convert it into an electric signal. Each detecting element (10) is associated with a respective collimator made of a material with a high atomic number and designed to block the gamma rays incident upon the detecting element (10) at a predetermined external solid angle (α, &bgr;, γ).
