With the development of the X ray machine, the x ray collimator is also evolving from simple to complex, with functions ranging from single to multi-purpose. Structurally, the early active collimator consisted of two teams of independently opened and closed lead leaves arranged in two layers perpendicular to each other.
The activity of each pair of lead leaves is centered on the X-ray center. The opening and closing of the lead leaves of the two teams respectively controlled the length and width of the irradiation field, and the purpose of flexibly adjusting the size and shape of the irradiation field was achieved.
In order to further improve the occlusion effect, the internal structure of the active collimator is increased from two groups of “#”-shaped lead leaves, and the upper and lower two groups of lead leaves in the same direction can synchronize activities, but their activities are different, and the purpose is to make The radiation fields formed by the lead beams of the two teams are always consistent.
In addition, a square tube is added between the two sets of lead leaves to absorb the scattered rays generated in the active collimator; the active collimator is also equipped with a filter plate for absorbing soft rays, and the filter plate of non-stop thickness can be replaced as needed. .
