Abstract

A compact gamma-camera has been constructed using a 3-mm-thick single NaI(Tl) crystal viewed by a 5-in-diameter Hamamatsu position-sensitive photomultiplier tube (R3292). In order to use this system in applications where the counting rate is high, such as in dynamic scintigraphy and industrial nondestructive testing, a fast data acquisition and processing system is very important. The design and operation of two fast data collection and processing systems capable of handling events within 30 μs 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 presented
