Embodiment Construction

[0060] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement them with reference to the description.

[0061] As a preference, a neutron capture therapy system and a treatment plan generating method thereof are embodiments of the present invention. The following will briefly introduce neutron capture therapy, especially boron neutron capture therapy.

[0062] The application of neutron capture therapy as an effective means of treating cancer has gradually increased in recent years, among which boron neutron capture therapy is the most common, and neutrons supplying boron neutron capture therapy can be supplied by nuclear reactors or accelerators. The embodiment of the present invention takes the accelerator boron neutron capture therapy as an example, and the basic components of the accelerator boron neutron capture therapy generally include an accelerator for...

Abstract

The invention discloses a radiotherapy system and a treatment plan generation method thereof. The radiotherapy system comprises a beam irradiation device, a treatment plan module and a control module. The beam irradiation device generates a treatment beam and irradiates an irradiated body to form an irradiated part, the treatment plan module generates a treatment plan according to parameters of the treatment beam and medical image data of the irradiated part, and the control module calls the treatment plan corresponding to the irradiated body from the treatment plan module, and controls the beam irradiation device to sequentially irradiate the irradiated body according to the at least two irradiation angles determined by the treatment plan generation method and the irradiation time corresponding to each irradiation angle. According to the radiotherapy system and the treatment plan generation method thereof, the radiation quantity of the shallow part of the irradiated part can be dispersed, and the radiation quantity of the deep part of a lesion tissue can be increased, so that the maximum dose of a normal tissue can be reduced, the minimum dose of the lesion tissue can be increased, and uniform distribution of the dose in the lesion tissue can be ensured.

Description

technical field [0001] One aspect of the present invention relates to a radiotherapy system; another aspect of the present invention relates to a method for generating a treatment plan, in particular to a method for generating a treatment plan for a radiotherapy system. Background technique [0002] With the development of atomic science, radiation therapy such as cobalt 60, linear accelerator, and electron beam has become one of the main means of cancer treatment. However, traditional photon or electron therapy is limited by the physical conditions of the radiation itself. While killing tumor cells, it will also cause damage to a large number of normal tissues along the beam path; in addition, due to the different sensitivity of tumor cells to radiation, traditional radiation therapy Treatment for more radioresistant malignant tumors (eg glioblastoma multiforme, melanoma) is often less effective. [0003] In order to reduce radiation damage to normal tissues around the tum...
