Scintillation detector with photosensor adjacent to signal processor - both formed of amorphous or polycrystalline silicon of insulating coating inside one sidewall of open collimator

摘要

The beam (9) of radiation falls on a scintillator (3) in the base of a collimating collector (8) between two sidewalls (6,7). The scintillation produced is converted by the photosensor (4) into electrical signals for evaluation by the processor (5). The support (6) on which the photosensor (4) and processor (5) are mounted together forms one wall of the collector (8). It may contain Ta, W or Mo and is coated with an insulating layer on which the components (4,5) are juxtaposed. USE/ADVANTAGE - For computer tomography equipment or luggage checking appts. Simplified by elimination of separate supports for photosensor and processor.
