摘要

The X-ray television system has improved picture quality, and consists of a television camera (1) facing the X-ray apparatus (4) through the patient (2). The camera has an X-ray image intensifier (3) and is linked to a control centre (5) that controls the sync. and deflection signals. The output of the camera is recorded on a picture carrier (6) that has two heads for record and replay. A changeover switch (9) allows the upper picture half to be recorded on one (1) track and the lower picture half on the othr track (b). The heads are switched alternately to the viewing monitor.
