The function of the x ray collimator is to control the size of the X-ray field and the direction of X-ray emission. In this process, the lead leaf and the lens in the beam limiter play an important role, so the protection x ray collimator has to protect the two parts.
Lead leaf is the shielding layer of X-ray, lead has a blocking effect on X-ray, and the closing size of lead leaf determines the size of the field of X-ray emission. If there is a problem with the lead leaf of the x ray collimator, the lead leaf cannot be closed, X-ray It will leak out and radiate to the surrounding things.
The mirror in the x ray collimator is mainly used to reflect X-rays. In the process of using the x ray collimator, care should be taken to keep the lens clean. Do not touch it with hands. If there is dirt on the lens, it will affect the emission of X-rays. Directly affect the quality and dose of X-rays.
