With the development of the X ray machine, the x ray collimator has evolved from simple to complex in structure, with functions ranging from single to multi-purpose.
Tell us about the event X ray collimator today.
In order to make the selection and adjustment of the illumination field more flexible and convenient in use, the occlusion effect is continuously improved, and the active x ray collimator appears. Activity x ray collimator is more functional than human, it can continuously adjust the size of the illumination field, meet the occlusion requirements of various films at any distance, and is widely used in modern X ray machines.
Structurally, the early activity of the xray 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 x ray collimator is increased from two groups of “#”-shaped lead leaves, and the upper and lower groups of lead leaves in the same direction can move synchronously, but their activities are different, and the purpose is to The radiation fields formed by the two groups of lead leaves can always be consistent. In addition, a square tube is added between the two sets of lead leaves to absorb the scattered rays generated in the x ray collimator; the x ray collimator is also equipped with a filter plate for absorbing soft rays, and can be replaced with non-stop thickness as needed. Filter plate.
