Classification of collimators

The collimator is mainly to control the irradiation field of X-rays and control the radiation dose. At the bottom, try to narrow the projection range to avoid unnecessary doses; and can absorb some scattered rays to improve the impact of clarity. Among other things, it can indicate the projection center and the size of the projection field. Therefore, the beam limiter is an indispensable auxiliary equipment for X-ray projection and protection. It can also be a collimator or a beam limiter. collimators can be divided into three categories: manual, automatic, and fully automatic. Usually the portable machine chooses manual, and the gastrointestinal machine chooses electric. The fully automatic beam limiter is also called feedback electric beam limiter and dose beam limiter. What I understand is that the collimator is these categories, and the application of the collimator has become more and more widespread.
