Abstract :
A simple model is presented which is used to characterize positron-imaging systems employing annihilation coincidence detection. The model is particularly useful in describing sensitivity for true coincidences, vulnerability to accidental coincidences, and overall count-rate capability in systems made of arrays of discrete detectors. An example is given of a commercially available positron imaging system. A design layout is shown which meets performance goals. Actual system performance is described.
