Abstract

To produce a parallel-projection image on a planar array of gamma-ray detectors, the standard procedure is to use a parallel-hole collimator. An alternative presented here to place a pinhole array in front of the detector and to synthesize parallel projections from the pinhole data. This eliminates the physical blurring and distance-dependent resolution effects of collimators, and replaces them with the mathematical problem of estimating projection integrals. We provide conditions under which this can reasonably be done and show some examples.
