The invention discloses a collimator library of radiotherapy equipment. A collimator mechanism is installed on the large guide rail of the beam of the column, and the transmission mechanism composed of a pulley, a synchronous belt and a motor drives the collimator mechanism to slide in parallel on the large guide rail; the side of the collimator mechanism is equipped with a lift The collimator mechanism, another transmission mechanism composed of a pulley, a synchronous belt, and a motor drives the collimator mechanism with grab hooks at both ends to move in parallel on the small guide rail; from the selection collimator mechanism to the transmission mechanism direction In the collimator storage library parallel to the collimator lifting mechanism, there are 6 automatic stations and 12 manual stations arranged longitudinally, and a convex flat collimator is installed on each station. During treatment, collimators with different aperture sizes can be used to form energy clusters of appropriate shape and quantity for lesions with complex shapes and large volumes. The collimator of the automatic station can be automatically exchanged with the collimator used on the radiation device, and the movement of selecting the collimator and lifting the collimator mechanism is controlled by the computer.
Description
[0001] Technology area [0002] The invention relates to a radiation device, in particular to a collimator library of radiotherapy equipment. Background technique [0003] The number of collimators in existing radiotherapy equipment is between 2 and 7, which cannot be added during use, or manual exchange is required, which is cumbersome. Due to the lack of collimator varieties, the radiotherapy equipment has insufficient conformal ability during treatment, and has a single function, which is only used to adjust the size of the ray field of view. In the future, with the improvement of detection methods and the increase of small target cases, the number of single target treatments of different specifications will increase. For target areas with complex shapes and large volumes, some collimators with special shapes are required to generate energy groups that can be spliced. Therefore, the aperture and shape of the collimator must be in series. In addition, there should be a de...
