What is a beam limiter?
The beam limiter is an electromechanical optical device installed in front of the output window of the X-ray tube assembly, and it is an indispensable auxiliary equipment for X-ray projection and protection. Its main function is to control the radiation field of the output line of the x-ray tube, so as to reduce the projection range as much as possible and avoid unnecessary doses under the premise of satisfying x-ray imaging and diagnosis; and can absorb some scattered rays to improve the clarity of impact Spend.
The beam limiter is mainly composed of a transmission device, a horizontal variable lead blade, and a longitudinal variable lead blade; the outside is mainly composed of the lead blade opening and closing adjustment knob, the light field lamp button and the interface connected with the X-ray tube assembly.
In addition, the beam limiter can indicate the projection center and the size of the projection field of view. Therefore, the beam limiter is an indispensable auxiliary equipment for x-ray projection and protection.
