The collimator, also known as the beam limiter, is an electromechanical optical device installed in the output window of the tube sleeve of the x-ray tube assembly. The main function of the collimator is to control the output of the X-ray bulb tube under the premise of satisfying the X-ray imaging diagnosis. The radiation field of the line minimizes the projection range and avoids unnecessary doses. And can absorb some scattered light to improve image clarity. In addition, the collimator can also function as an indicator of the projection center and the size of the projection field of view.
This collimator is mainly used for fixed X-ray machines, mainly matched with 150 KV X-ray tubes.
