Normally, the beam limiter is installed under the medical tube. The X ray collimator is an electromechanical optical device mounted in front of the X-ray tube assembly sleeve output window. Its main function is to control the illumination field of the X-ray tube output line so as to meet the requirements of X-ray imaging and diagnosis. Next, try to reduce the projection range, avoid unnecessary doses; and absorb some scattered rays to improve image clarity. In addition, it can indicate the size of the projection center and the projected field of view. Therefore, the beam illuminator is an indispensable auxiliary device for X-ray projection and protection. What does the X ray collimator look like, as shown in the following figure:
The picture above is the X ray collimator. Is it very cute? Returning to the topic, the X ray collimator uses a special connector to be integrated with the flange of the sleeve window and can be rotated within a certain range. The focus position required by the X ray collimator and the focus of the actual X-ray tube assembly during installation. The location is consistent. With the development of X-ray machine mainframes, X ray collimator is also evolving from simple to complex, functionally from singular to multi-purpose, with electric X ray collimator, simple X ray collimator, manual X ray collimator And so on.
