The X-ray collimator controls the field size of X-ray and the direction of X-ray emission. In this process, the lead leaf and lens play an important role in the X-ray collimator, so the two parts should be protected while the X-ray collimator is protected.
The lead leaf is the X-ray shield. Lead blocks X-rays. The closed size of the lead leaf determines the size of the X-ray field emitted. If there is a problem with the guide vanes for beam alignment, the guide vanes cannot be closed. X-rays will leak and radiate to surrounding objects.
The reflector in X-ray collimator is mainly used to reflect X-ray. In the process of using the beam collimation, the lens should be kept clean and do not touch with hands. If there is dust on the lens, it will affect the X-ray emission, and directly affect the quality and dose of X-ray.
