The electronic collimation is an electromechanical optical device installed in front of the output window of the tube sleeve of the X-ray tube assembly. Its main function is to control the irradiation field of the output rays of the X-ray tube, so as to minimize the projection range and avoid unnecessary doses on the premise of satisfying X-ray imaging and diagnosis, and to absorb some scattered rays and improve them. Image definition. In addition, it can indicate the size of projection centers and projected horizons. Therefore, the electronic collimation is an indispensable auxiliary device for X-ray projection and protection.
The electronic collimation has manual restraint, electric electronic collimation and automatic electronic collimation.
