A METHOD FOR EVALUATING RADIATION MODEL DATA IN PARTICLE BEAM RADIATION APPLICATIONS

摘要

A method for evaluating radiation model data in particle beam radiation applications, in particular in proton beam therapy of a determined target volume of malign tissue within a creature, is disclosed, comprising the steps of: a) gaining diagnostic data for a determined target volume to be irradiated; b) calculating a particle range in the predetermined target volume based on the diagnostic data for the determined target volume; c) designing a radiation model comprising particle beam characteristics based on the calculated particle range and optionally on a calculated dose depth distribution; d) applying a single pencil beam shot to the determined target volume at an elevated beam energy as compared to the particle beam characteristics of the radiation model; e) measuring the beam range of the single pencil beam shot downstream of the determined target volume; and f) comparing the measured beam range to a reference beam range calculated on the basis of the radiation model.
