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 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 provided
