The kinds of x ray collimator are divided into beam limiters for 125KV and 150KV tubes.
The kinds of beam limiters are divided into three types: manual beam limiters, electric beam limiters and automatic beam limiters. Manual, electric and automatic beam limiters work in the same way. They all change the X-ray field by controlling the closure of the lead leaf in the beam limiter by controlling the button. The instrument panel is on the beam limiter. The manual beam limiter is called manual beam limiter, in which the human controls the turning knob and opens the beam limiter to control the size of the irradiation field. Functionally integrated into the console, an electric beam limiter that controls the size of the irradiation field is called an electric beam limiter. The automatic beam limiter has the function of automatically adjusting the size of the irradiation field.
The kinds of beam limiters are divided into fixed X-ray machines, mobile X-ray machines and portable X-ray machines.
