collimated light function

In the x ray collimator, the collimated light plays an important role. It can simulate and locate the X-ray, adjust the closure of the lead leaf and the position of the beam limiter by radiating the simulated light, so as to determine the dose of the X-ray to be radiated and the irradiation position, and make the collimated light play a pre-set role. Because X-ray radiation, the greater the dose of the greater damage, so can not be random to the human body, collimated light to simulate X-ray positioning adjustment, but also to protect the irradiated. The collimated light is halogen lamp and LED lamp, the halogen lamp is the lamp which the beam limiter used in the early days, has been slowly replaced by LED lamp, LED lamp has been widely used.
