Computer-Camera Interface

Abstract

A device using operational amplifiers has been constructed to improve the interfacing of scintillation cameras to a scintigraphic data analysis computer. Advantages of the device are that (A) distortion of pulses is eliminated, (B) the data store/playback unit may be used as a signal source, (C) proper orientation of signals sent to the computer is automatic, and (D) long transmission lines between the computer and scintillation cameras may be used.
