Abstract
The present disclosure provides a positioning assembly for a radiation irradiation system. The positioning assembly includes a shielding body made of polymer and radiation shielding material capable of shielding the radiation and a sealing bag for accommodating the shielding body, when the target to be irradiated is placed on the positioning assembly, the positioning assembly is recessed with a shape of the target at the position where the target is placed and forms a contour corresponding to the target to position the target to be irradiated.
Claims20
A radiation irradiation system comprising:
- a radiation irradiation device, wherein the radiation irradiation system is a neutron capture therapy system, the radiation irradiation device is a neutron capture therapy device including a neutron source for generating a mixed radiation field including neutrons and photons;
- and
- a treatment bed for transporting a target to be irradiated to the radiation irradiation device for irradiation, wherein the treatment bed comprises:
- a mounting table on which the target to be irradiated is placed;
- a supporting portion for supporting the mounting table;
- and
- a positioning assembly provided on the mounting table for positioning the target to be irradiated, wherein the positioning assembly is configured to be reused and comprises:
- a shielding body including polymer and radiation shielding material capable of shielding the radiation, the shielding material is neutron capture material, the neutron capture material is capable of shielding neutrons and is made of at least one of boron-containing compound or lithium-containing compound;
- and
- a sealing bag for accommodating the shielding body,
- when the target to be irradiated is placed on the positioning assembly, the positioning assembly is recessed with a shape of the target at the position where the target is placed and forms a contour corresponding to the target to position the target to be irradiated.

A radiation irradiation system comprising:
- a radiation irradiation device, wherein the radiation irradiation system is a neutron capture therapy system, the radiation irradiation device is a neutron capture therapy device including a neutron source for generating a mixed radiation field including neutrons and photons, the shielding material is neutron capture material;
- a treatment bed for transporting a target to be irradiated to the radiation irradiation device for irradiation;
- and
- a positioning assembly for positioning the target to be irradiated,
- wherein the positioning assembly is configured to be reused and defines a first state and a second state, when the positioning assembly is in the first state, the positioning assembly is not deformed or maintained in the first state deformed by external pressure;
- and when the positioning assembly is in the second state, the positioning assembly is deformed or maintained in a second state deformed by external pressure different from the first state deformed by external pressure, so as to improve the treatment effect for avoiding the movement of the target by deforming or maintaining the two different states, the positioning assembly is capable of restoring to the state before the target is placed on the positioning assembly.
