Abstract: A radiotherapy system and a therapy plan generation method therefor. The radiotherapy system includes a beam irradiation apparatus, a therapy plan module, and a control module. The beam irradiation apparatus generates a beam for therapy and irradiates an irradiated body to form an irradiated part. A tissue model template library of the irradiated body is stored in the therapy plan module; the therapy plan module performs dosage simulation calculation according to the tissue model template library, medical imaging data of the irradiated part, and a parameter of the beam for therapy generated by the beam irradiation apparatus, and generates a therapy plan. The control module retrieves, from the therapy plan module, the therapy plan corresponding to the irradiated body, and controls the beam irradiation apparatus to irradiate the irradiated body according to the therapy plan determined by the therapy plan generation method.

Abstract: A boron neutron capture therapy (BNCT) system includes a neutron beam irradiation device, a treatment planning module, and a control module. The neutron beam irradiation device is used to generate a therapeutic neutron beam during irradiation therapy and irradiate same to an irradiated body that has ingested a boron (10B)-containing drug so as to form an irradiated site. According to medical image data of the irradiated site and a parameter of the therapeutic neutron beam generated by the neutron beam irradiation device, the treatment planning module performs a dosage simulation calculation and generates a treatment plan, the medical image data of the irradiated site comprising tissue-related information and boron (10B) concentration-related information. The control module retrieves, from the treatment planning module, a treatment plan corresponding to the irradiated body, and controls the neutron beam irradiation device to perform irradiation therapy on the irradiated body according to the treatment plan.
