如图1所示，医疗设备除包括上述的机架和滚筒1以外，还可以包括设置于滚筒1上的聚焦治疗头2。聚焦治疗头2凸出于治疗空间11内，使得治疗空间11小，使患者运动和设备回转受到制约。As shown in FIG. 1 , in addition to the above-mentioned frame and drum 1 , the medical device may also include a focusing treatment head 2 disposed on the drum 1 . The focusing treatment head 2 protrudes out of the treatment space 11 , so that the treatment space 11 is small, and the movement of the patient and the rotation of the equipment are restricted.

The first moving collimator 232 is provided with a plurality of first collimation channel groups Q1, and the first collimation channel group Q1 includes a plurality of first collimation channels q1. In the plurality of first collimation channel groups Q1, each group of first collimation channel groups q1 has different apertures and/or shapes of the apertures. As shown in FIGS. 4 , 5 , 6 and 7 , the first moving collimator 232 is movable relative to the source body 22 between a first state S1 and a second state S2 , the first state S1 including the first state S1 Any one of the first collimation channel groups Q1 on the mobile collimator 232 corresponds to the through hole 221 . That is, when the first moving collimator 232 is in the first state S1, one first collimation channel group Q1 on the first moving collimator 232 is in the working position. The second state S2 includes the orthographic projection of the source body 22 on the plane where the first moving collimator 232 is located, and there is no overlap with the first moving collimator 232 . That is, when the first moving collimator 232 is in the second state S2, each first collimation channel group Q1 on the first moving collimator 232 is in a position other than the working position, and the through holes are The position forms an avoidance.

其中，对以上第一移动准直器232相对于载源体在第一状态S1和第二状态S2之间运动的方式不做具体限定，只要该第一移动准直器232处于第一状态S1的情况下，第一移动准直器232上的一个第一准直通道组Q1与通孔221对应。该第一移动准直器232处于第二状态S2的情况下，第一移动准直器232上的每个第一准直通道组Q1均对通孔所在位置形成避让即可。示例的，第一移动准直器232可以通过转动、平移或者两者的组合方式在第一状态S1和第二状态S2之间运动。The manner in which the first moving collimator 232 moves between the first state S1 and the second state S2 relative to the source body is not specifically limited, as long as the first moving collimator 232 is in the first state S1 In the case of , a first collimation channel group Q1 on the first moving collimator 232 corresponds to the through hole 221 . When the first moving collimator 232 is in the second state S2, it is sufficient that each first collimation channel group Q1 on the first moving collimator 232 avoids the position of the through hole. Illustratively, the first moving collimator 232 may move between the first state S1 and the second state S2 through rotation, translation, or a combination of the two.

在本公开提供的聚焦治疗头2中，在第一移动准直器232处于第一状态S1的情况下，第一移动准直器232与通孔221对应，可以为放射性射线提供一定长度的准直通道，对放射性射线进行聚焦，这时，如图6所示，聚焦治疗头2可以处于工作状态，伸入治疗空间11内。而在第一移动准直器232处于第二状态S2的情况下，如图7所示，第一移动准直器232对通孔所在位置形成避让，这时，聚焦治疗头2可以处于非工作状态，移出治疗空间11。从而能够对治疗空间11形成避让，解决了相关技术中聚焦治疗头2凸出于治疗空间11，使得治疗空间11小，并在聚焦治疗头2处于非工作状态时，患者运动空间和设备回转治疗转速受到制约的问题。可以提高转速，并提高设备利用率。In the focusing treatment head 2 provided by the present disclosure, when the first moving collimator 232 is in the first state S1, the first moving collimator 232 corresponds to the through hole 221, and can provide a certain length of collimator for the radioactive rays A straight channel is used to focus the radioactive rays.

When the first moving collimator 232 is in the second state S2, as shown in FIG. 7 , the first moving collimator 232 avoids the position of the through hole, and at this time, the focusing treatment head 2 can be in a non-working state. state, move out of the treatment space 11. Therefore, the treatment space 11 can be avoided, which solves the problem that the focus treatment head 2 protrudes out of the treatment space 11 in the related art, so that the treatment space 11 is small, and when the focus treatment head 2 is in a non-working state, the patient movement space and the equipment are rotated for treatment. The speed limit is the problem. It can increase the speed and improve the utilization rate of the equipment.

在一些实施例中，第一移动准直器232沿第一方向(如图4、图5、图6和图7中箭头a所示方向)移动，第一方向垂直于准直器组件23的厚度方向。也即，第一移动准直器232为采用平移的方式进行运动。In some embodiments, the first moving collimator 232 moves in a first direction (the direction indicated by arrow a in FIGS. 4 , 5 , 6 and 7 ), the first direction being perpendicular to the direction of the collimator assembly 23 thickness direction. That is, the first moving collimator 232 moves in a translation manner.

其中，对以上第一移动准直器232中多个第一准直通道组Q1的排列方式不做具体限定。Wherein, the arrangement manner of the plurality of first collimation channel groups Q1 in the above first moving collimator 232 is not specifically limited.
