SCINTILLATOR PANEL HAVING UNIFORM OUTPUT RESPONSE

摘要

A scintillator panel assembly for gamma ray detection includes a scintillator panel having fluorescent material therein for generating a photon when a gamma ray enters the panel, and one or more non-scintillating segments embedded in opposing edges of the scintillator panel which conduct light but do not generate a photon when a gamma ray enters. One or more photon detectors, such as photomultiplier tubes, are disposed immediately adjacent the one or more non-scintillating segments for receiving photons conducted through the non-scintillating segments. The non-scintillating segments preferably have optical transmission and reflection properties that are substantially the same as the optical transmission and reflection properties of the scintillator panel. This configuration provides substantially uniform light output response for all photon generation locations which results in improved spectral resolution.
