Abstract

A compact gamma-camera is constructed using a 3-mm-thick single NaI(Tl) crystal viewed by a 5-in-diameter position-sensitive photomultiplier tube. In order to use this system in applications where the counting rate is high and flexibility of data handling is desired, a faster data acquisition and processing system is required. The design and operation of two data collection and processing systems capable of handling events within 30 mu s are presented. One of the systems is based on the use of a commercial Vector 32C/8500 processor board, while the other makes use of multiple T805 transputers. A comparison of the two systems is provided.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
