The x ray collimator housing is ferrous and the multi-function square view X-ray beamer system is stable.
In order to ensure that the x ray collimator can emit X-rays in an appropriate amount, the outer wall of the beam limiter is made of double-lead lead material. The x ray collimator uses lead leaf to control the size of the X-ray field, and the blades are also lead-lined. Two pairs of lead leaves are at the entrance of the ray, two pairs of lead leaves are in the middle, two pairs of lead leaves are at the ray exit, and six lead leaves are in the x ray collimator. A knob on the outside of the x ray collimator controls the manual rotation to control the blade.
The lower side of the x ray collimator has a scale that measures the distance to the bed surface so that the SID can be estimated.
