ABSTRACT:
A system wherein a video camera views an optical version of an x-ray image and displays it in a circular pattern on a television screen and a photographic camera is arranged for simultaneously recording the image on film. A circuit is provided for generating signals that are added to the composite video signal for writing a bright outline of the photo camera frame on the television screen so that the user can determine what parts of the x-ray image are within the camera film frame boundaries.
