APPARATUS FOR INDICATING THE POSITION OF A REFERENCE MARKER USED IN A GAMMA RAY CAMERA

摘要

Apparatus for indicating the position of a reference marker is adapted for use with a medical gamma camera. A movable reference marker is coupled to a fixed reference member by an arm, and x and y co-ordinate voltages are generated and fed to a display screen of the gamma camera to produce a reference mark on the screen corresponding to the position of the marker.
