Abstract
A compact gamma-camera has been constructed using a 3 mm thick single NaI(Tl) crystal viewed by a 5 inch diameter Hamamatsu position-sensiti ve photomultiplier tube (R3292) [1, 2]. In order to use,this system in applications where the counting rate is high, and at the same time fl exibility of data handling is desired, a faster data acquisition and p rocessing system is required. The. design and operation of two data co llection and processing systems capable of handling events within 30 m us are presented. One of the systems is based on the use of a commerci al Vector32C/8500 processor board whilst the other makes use of multip le T805 transputers. A comparison of the two systems is provided.
