Abstract

The invention provides a deceleration filter device and a neutron radiation therapy system, which relate to the technical field of medical devices and solve the problem of inconvenient setting of neutron deceleration effects according to the needs of treating patients with different lesion depths. The deceleration filter device includes: a bearing box and a plurality of deceleration parts for reducing the neutron flux, the bearing box is arranged between the core and the irradiation port, the top of the bearing box is provided with an opening, and a plurality of Placement position, a plurality of deceleration parts are placed in the placement position in turn, the deceleration parts are provided with lifting lugs, and the carrying case is provided with handles. The deceleration filter device is applied to the neutron radiation therapy system, and the deceleration effect of the deceleration filter device can be changed by changing the number or material of the deceleration parts, thereby changing the reachable depth of the neutron beam, so that various lesions can be completed in the same treatment room. Deep treatment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a deceleration filter device and a neutron radiation therapy system. Background technique [0002] The existing neutron radiation therapy system uses a proton accelerator to irradiate a target to generate neutrons as a neutron source or a nuclear reactor as a neutron source, and the center of the neutron source is aimed at the lesion position of the patient for radiation therapy. [0003] The accelerator in this system is usually a linear accelerator, and the outlet of the accelerator is located in the treatment room for performing radiation therapy on the patient. For different lesion depths, the required neutron beam energy is different. For example, thermal neutron beams are required for cortical tumor irradiation, and epithermal neutron beams are required for human deep tumor irradiation. Therefore, in order to treat patients with different lesion depths, it is neces...
