The number of the ring buttons 30 is not particularly limited in the present application, as long as the inner ring structure 1 and the outer ring structure 2 can be assembled with the collimator 5 through the mounting structure 3.

The movement of the outer ring structure 2 relative to the inner ring structure 1 can be limited by pressing the positioning column 8 on the inner ring structure 1, thereby further realizing the locking and fixing of the foot collimator 5. When the outer ring structure 2 needs to be rotated, the motion limit can be released only by pulling up the positioning column 8. In other words, before the foot collimator 5 is mounted or before the foot collimator 5 is removed, the positioning posts 8 may be pulled up so that the outer ring structure 2 and the inner ring structure 1 are in a state capable of relative movement. When the installation of the legged collimator 5 is completed, the positioning posts 8 may be inserted so that the outer ring structure 2 and the inner ring structure 1 are in a locked state.

An embodiment of the present application provides a neutron capture therapy device including a beam shaper assembly; and the collimator 5 mentioned in any of the above embodiments.

In the actual treatment process of the neutron capture treatment device, the tumor sizes and tumor positions of different patients are also different, the requirements on the irradiation range of the neutron beam are also different, and the limitation of the irradiation range of the neutron beam is directly related to the collimator 5, so that the collimator 5 with different calibers is needed for tumors in different situations. Also, the relative position between the collimator 5 and the tumor needs to be adjusted according to the specific situation, so as to facilitate the irradiation of the tumor by the neutron capture treatment device. In the neutron capture treatment device provided by the embodiment of the application, the collimator 5 can be installed and disassembled by one person without using any other tool, so that the working efficiency is improved. Meanwhile, the operation of manually screwing the bolt 7 is changed into mechanical structure limiting and fixing, and the operation precision and the radiation treatment reliability of the neutron capture treatment device are improved. In addition, the wear resulting from multiple removals of the collimator 5 from the beam shaper assembly may improve the economy and stability of the overall neutron capture therapy device by periodic replacement of wear members.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated, whereby features defining "first," "second," or the like, may explicitly or implicitly include at least one such feature.
