NUMEDICS: a system for on-line data processing in nuclear medicine.

A multiterminal system --NUMEDICS--has been developed to study the problems of on-line acquisition, processing, and display of scintigraphic data. The hardware-software configuration of NUMEDICS permits simultaneous and independent operation of terminals in the Division of Nuclear Medicine, the Physics Research Laboratory, and the Cyclotron Laboratory of the Massachusetts General Hospital. This paper describes the hardware and software developments in NUMEDICS which have been proven to be of value in clinical and research applications. These features are illustrated by applications to the evaluation of left ventricular performance, three-dimensional imaging, and functional imaging of rCBF.
