Abstract
A gamma ray imaging system for providing high resolution images includes a collimator plate with an array of multiple holes which image a gamma emitting object onto a semiconductor gamma detector pixel array coupled to a signal processor. The collimator holes are smaller than half the pixel pitch. The detector array is moved in steps, with a step-size equal to the pitch of the collimator holes, to successive imaging positions. The hole locations and imaging positions are such that gamma photons do not fall on the dead areas of the pixels. An electronic processing unit constructs from the pixel signals produced at each imaging position, a set of independent equations and solves them to derive the exact image signal of each irradiated area, and uses this data to compose and a display a high resolution gamma image of the object.
