AB The potential of the Anger scintillation camera cannot be fully realized unless data are recorded at the time of the patient study. Since many small nuclear medicine centers do not have access to a digital computer, there is a need for a simple and economical method to record and process data. A system has been developed that records static and dynamic scintigrams, without loss of image quality, where modified data from the camera are recorded on a modern video-cassette recorder in serial digital form. Results are presented showing the preservation of image quality at increasing count densities on a 127 × 127 digital matrix. Region-of-interest information may be extracted from the recorded data for simple indices or time-activity studies, alternatively, the stored digital data may be passed to a computer for further, more sophisticated processing.
