Abstract: Radiation emitted from a subject positioned on a programmable X, Y platform is detected by means of an array of sensing devices. The platform, which is in spaced relationship with the subject, is moved along its X and Y axes in incremental steps defining a programmed scanning pattern, each step being an integral multiple of the distance between adjacent sensing devices. The radioactive events, which are detected at each step, are temporarily held in a memory and then stored on a recording medium. Upon completion of the programmed scanning sequence, the stored data which represents the radioactivity detected at each step is recalled from the recording medium and applied to a display via the memory for presentation as a combined pictorial representation of the detected radioactive events at each step.
