How much do you know about the principle of the beamer? The beamer, 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 beamer is mainly connected with the bulb. The function of the device is to perform positioning during positioning, simulate the radiation area of X-rays, reduce the radiation dose of the patient, and enhance the image quality. The principle of the beamer is to control the irradiation field of the output line of the X-ray bulb tube under the premise of satisfying the X-ray imaging diagnosis, so as to minimize the projection range and avoid unnecessary doses. And can absorb some scattered light to improve image clarity. In addition, the beamer can also indicate the projection center and the size of the projection field of view. Therefore, the x-ray beam optical device is an indispensable auxiliary device for x-ray irradiation and protection.
