Abstract

A detector for a nuclear imaging system includes a scintillator including an array of scintillator elements and a light guide including a grid which defines light guide elements. Light from scintillations in the scintillation crystal in response to received radiation, passes through the light guide and strikes light sensitive elements of a light sensitive element array. The light sensitive element array includes larger elements in an array in the center surrounded by smaller light sensitive elements located in a peripheral array around the central array.
