Boron neutron capture therapy system and treatment plan generation method therefor

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 (B)-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 (B) 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.
