The function of x ray collimator is to control the size of X-ray field and the direction of X-ray emission. In this process, the lead leaf and lens in the beam limiter play a very important role, so the protect x ray collimator must ensure the lead leaf and lens of the beam limiter.
Lead leaf is the shielding layer of X-ray. Lead blockades X-ray. The closure size of lead leaf determines the size of X-ray field. If there is a problem with the lead leaf of the beam limiter, the lead leaf can not be closed, and X-ray will leak out and radiate the surrounding things. Protecting the lead leaf of the beam limiter is very important for protect x ray collimator.
Reflector in beam limiter is mainly used to reflect X-ray. In the process of using beam limiter, attention should be paid to keeping the lens clean and not touching with hands. If there is dirt on the lens, it will affect the emission of X-ray, and directly affect the quality and dose of X-ray. Protecting the reflector of the beam limiter is very important for protect x ray collimator.
