Abstract
A modular solid state x-radiation detector. A detector array is made up of a plurality of collimator plates having pockets formed in the planar surfaces thereof to carry scintillator bars, and dimensioned so that the edges of the scintillators are shielded by the pockets, yielding several advantages. Wider scintillator bars are thus possible, increasing quantum detection efficiency while guarding against energy dependent punch through at the edges of the scintillator, thereby to enhance spectral linearity. The arrangement also prevents x-rays from bypassing the scintillator, thus protecting the adhesive which bonds the scintillator to the plate and the photodiodes mounted behind the scintillator. A further benefit is an increase in optical transfer of light to the rear of the scintillator where the diode is mounted since there is a less severe aspect ratio of depth to width, reducing the number of reflections encountered by light travelling to the photodiode. The collimator plates are also provided with opposed legs which engage slots in a photosensor assembly to accurately align the photosensor and scintillator.
