The ceramic x ray collimator holder, also known as the “shield”, “dimmer” or “beam illuminator”, is mounted in the x-tube sleeve window to mask unwanted primary x-rays during X-ray inspection. It limits the x-ray field to the minimum required range, minimizing the amount of x-ray exposure the patient receives. The main role of the beam limiter is to limit the field of illumination so that the patient and the operator receive as little radiation as possible. Reduce the area where secondary rays are generated, and improve the clarity of the perspective and the film. Block leaking rays.
The operation of the ceramic x ray collimator holder is very simple and has a great effect. The choice of the limiter can be selected by the type of root tube and ceramic x ray collimator holder!
