What is the function of the x ray collimator?

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