Method of protecting beam limiter

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 protecting beam limiter should protect the lead leaf and lens.

Lead leaf is the shielding layer of X-ray. Lead has a blocking effect on X-ray. The closure size of lead leaf determines the size of the field of X-ray emission. If the lead leaf of the beam limiter is not closed, X-ray will leak out and radiate the surrounding things. Protecting the beam limiter must protect the lead leaf.
Reflectors in beam limiters are mainly used to reflect X-rays. In the process of protecting 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-rays and directly affect the quality and dose of X-rays.
