A Tracking Television System for Medical Applications

Publisher Summary This chapter provides an overview of a tracking television system for medical applications. The new measuring television system is developed using an electrostatic image dissector. The system is able to measure the two dimensional motions of one or more objects simultaneously with a very high sampling rate. The system has been designed to be able to produce X–Y coordinate signals of up to eight points on which special target marks brighter than background have been attached. The sampling frequency can be raised to 15.75 kHz. One of the most important features of the system is in the novel scanning method, which enables high speed measurement and monitoring to be affected simultaneously. The ability to monitor the image facilitates the adjustment of the field of view and optical focus. In order that a time-sharing method can be employed in the scanning regime adopted, an electrostatic deflection image dissector is used. The system can measure up to eight points simultaneously in the same field of view with a high rate of response. In one application, to study physical motion use has been made of two television systems. The present equipment is considered to have applications both in industrial and medical fields.
