Abstract
In a radioactivity distribution detection system of the kind for determining the location and distribution of radioactive events emitted from a subject under diagnosis, the improvement of electrically isolating the subject from the potentially harmful effects of leakage currents. The improvement comprises a first converter for converting electronic data signals representing the location and distribution of radioactive events to optical signals, a coupler for effecting an optical path of transmission for the converted optical signals, and a second converter for converting the transmitted optical signals to electronic data signals so that they can be processed to provide a presentation of the distribution of the sensed events. Preferably, the coupler comprises a pair of fiber optic cables for complete, duplex and bidirectional transmission of optical signals. The coupler allows the processing console to be far removed from the sensors and detectors of the radioactive events. The coupler also allows a reduction in the bulk and weight of such systems while enhancing their transmission capability. The coupler effectively protects a subject under diagnosis from the potentially harmful effects of leakage currents emanating from the processing console.
