Abstract

The embodiment of the invention discloses a beam evaluation method apparatus, and equipment for boron neutron capture therapy, and a storage medium. The method comprises the following steps: acquiringa neutron energy spectrum to be evaluated and a photon energy spectrum to be evaluated in the same epithermal neutron beam; inputting energy values of a plurality of sets of monoenergetic neutrons inthe neutron energy spectrum to be evaluated into a first depth dose model and a second depth dose model, to obtain a plurality of sets of first curve data and a plurality of sets of second curve data, and sequentially inputting energy values of a plurality of sets of single-energy photons in the photon energy spectrum to be evaluated into a third depth dose model to obtain a plurality of sets ofthird curve data; through the plurality of sets of first curve data, determining the plurality of sets of second curve data and the plurality of sets of third curve data, the dominant depth and the therapeutic gain to evaluate the therapeutic effect of the epithermal neutron beam, so that the evaluation efficiency of the therapeutic effect of the epithermal neutron beam is effectively improved, and the beneficial effect of the rapid adjustment of the neutron shaping device is realized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of radiotherapy, and in particular to a beam evaluation method, device, equipment and storage medium for boron neutron capture therapy. Background technique [0002] With the rapid development of modern medical technology, boron neutron capture therapy has been widely used in clinical medicine. [0003] BNCT (Boron Neutron Capture Therapy, Boron Neutron Capture Therapy) is a bio-targeted radiotherapy mode with "inherent" safety, by injecting non-toxic boron-containing drugs with pro-tumor tissue into human blood, waiting for boron drugs to After being enriched in tumor tissue, epithermal neutrons are used to irradiate the tumor site. Epithermal neutrons enter human tissue and slow down into thermal neutrons, which can interact with 10 The B nuclide undergoes a radiation capture reaction, releasing α particles ( 4 He) and lithium particles ( 7 Li). Due to the short range of these pa...
