The invention relates to a beam evaluation method for
boron neutron capture therapy, a beam evaluation device for
boron neutron capture therapy, an apparatus and a storage medium. The method includesthe following steps that: a
neutron energy spectrum to be evaluated and a
photon energy spectrum to be evaluated in an
epithermal neutron beam are separately divided into a plurality of sub-energy-spectrum intervals; the
fluence of the sub-energy-spectrum intervals in the
neutron energy spectrum to be evaluated is obtained and is adopted as first
fluence, and the
fluence of the sub-energy-spectrumintervals in the
photon energy spectrum to be evaluated is obtained and is adopted as second fluence; the first fluence is substituted into a first
depth dose formula and a second
depth dose formulaseparately, so that first curve data and second curve data are obtained, and the second fluence is substituted into a third
depth dose formula, so that third curve data are obtained; and dominant depth and treatment
gain are determined according to the first curve data, the second curve data and the third curve data, so that the
therapeutic effect of the
epithermal neutron beam is determined. Withthe beam evaluation method for
boron neutron capture therapy, the beam evaluation device for boron
neutron capture therapy, the apparatus and the storage medium adopted, the evaluation effectivenessof the
therapeutic effect of the
epithermal neutron beam can be effectively improved, and a neutron shaping device can be quickly adjusted.
