Abstract: A radiation detector, in particular a gamma camera, is constructed and operated in such a fashion that only a predetermined number of light sensors (such as PMT's) adjoining each other in a cluster are used to generate a signal with amplitude and event position information. The camera may also use an array of individual scintillation elements (crystals) in place of a single crystal, with certain advantages obtained thereby. According to another aspect of the invention, there is a reflector sheet that defines an array of apertures through which scintillation light can pass from the scintillation crystal to a plurality of light sensors optically coupled to an optical window in an array corresponding to the array of apertures in the reflector.

Abstract: A radiation detection system can include a first material to produce a first light in response to receiving a target radiation. The radiation detection system can also include a second material to propagate a second light to a first end of the second material and to a second end of the second material, in response to receiving the first light. The radiation detection system can also include a reflector coupled to the first end of the second material. In an embodiment, the reflector can reflect the second light, so that the reflected second light can be received by a photosensor coupled to a second end of the second material.
