The radiation field formed by the two pairs of lead leaves of the X-ray collimator is always consistent

In order to make the selection and adjustment of the irradiation field more flexible and convenient in use, and to continue to improve the shielding effect, a movable X-ray collimator appeared. In the positioning with the tube sleeve, the X-ray collimator adopts a special connection piece to be fixed and integrated with the flange plate of the tube sleeve window, and can be rotated within a certain range. The focus of the X-ray collimator when installed The position is consistent with the focus position of the actual X-ray tube assembly. Here are some common X-ray collimator:


In order to further improve the shielding effect, the internal structure of the X-ray collimator is increased from one group of “#” shaped lead leaves to two groups. The upper and lower pairs of lead leaves in the same direction can move simultaneously, but their activity ranges are different.

The active X-ray collimator is more advantageous. It can continuously adjust the size of the irradiation field to meet the requirements of various sizes of shielding at any distance. It is widely used by modern X-ray machines. The movement of each pair of lead leaves is symmetrical with the X-ray center. The opening and closing of the two pairs of lead leaves controls the length and width of the irradiation field, and can flexibly adjust the size and shape of the irradiation field. The purpose is to keep the radiation fields formed by the two pairs of lead leaves always consistent. A square tube is added between the two sets of lead leaves to absorb scattered rays; the X-ray collimator is also equipped with a filter plate that absorbs soft rays, and the filter plate of non-stop thickness can be replaced as needed.
