A computer controlled high resolution radioactivity distribution detection system is provided for sensing radioactive events in a biological specimen. The system includes a rotating disc memory which contains instructional data for controlling the computer. Radiation emitted from a subject positioned on a programmable XY platform is directed through a collimator and is detected by means of an array of sensing devices and front end electronics. The detected radioactive events are temporarily held in a buffer memory under control of the computer for storage. The temporarily stored data is fed via the computer to a disc memory for long term storage, a disc controller constitutes an interface to the disc memory. The stored data is then applied to a display via computer for presentation.
