The collimator is an accessory part of the X-ray inspection equipment. The main purpose is to position it when it is set up to simulate the X-ray radiation area, which can reduce the patient’s radiation dose and enhance the image quality.
The collimator, as its name implies, acts to shrink the beam. The actual function is to first turn on the light on the beamer, and adjust the knobs of the X and Y directions of the collimator, so that the light of the collimator shines on the film box of your machine, so that the size of the light field is exactly the size of the film. Consistent, and then you can film. Because the machine must adjust the X-ray field and light field to a minimum deviation before leaving the factory, this light field can simulate the invisible X-ray field.
