Boron neutron capture therapy system and treatment plan generation method therefor

A method for generating a treatment plan of a boron neutron capture therapy (BNCT) system, characterized in that the method comprises:

• establishing a corresponding three-dimensional (3D) voxel prosthesis tissue model with tissue type data according to tissue-related information of medical imaging data of an irradiated site;
• giving boron concentration data of each voxel unit in the 3D voxel prosthesis tissue model according to boron concentration-related information of medical imaging data of the irradiated site;
• defining beam parameters in a Monte Carlo simulation program, and performing dose simulation and calculation by sampling of different irradiation angles;
• and
• performing an optimum selection to the irradiation angles according to a calculation result, to generate the treatment plan.

A boron neutron capture therapy (BNCT) system, characterized in that the BNCT system comprises:

• a neutron beam irradiation device generating a treatment neutron beam during irradiation treatment and irradiates the treatment neutron beam to an irradiated body who has ingested a boron (1°B)-containing drug, to form an irradiated site;
• a treatment plan module defining tissue type and establish a 3D voxel prosthesis tissue model with tissue type data according to medical imaging data of the irradiated site, and giving boron concentration data to different types of tissues of the 3D voxel prosthesis tissue model, and giving different boron concentration data to tissues of the same type;
• and the treatment plan module performing dose simulation and calculation and generating treatment plans according to the 3D voxel prosthesis tissue model, the boron concentration data and parameters of the treatment neutron beam generated by the neutron beam irradiation device;
• and
• a control module retrieving a respective one of the treatment plans corresponding to the irradiated body from the treatment plan module, and controlling the neutron beam irradiation device to perform irradiation treatment on the irradiated body according to the respective one of the treatment plans.
