摘要A method is provided for evaluating a procedure for determining an aggregate radiotherapy dose received in the course of a radiotherapy treatment. The method includes: defining a deformable model of at least one organ to be treated and of at least one neighboring organ, generating a series of simulated images, interpretable by the procedure to be evaluated, with aid of the model; comparing the aggregate dose calculated by the procedure to be evaluated, applied to at least one of the simulated images, with a reference aggregate dose, so as to deliver at least one item of information representative of the quality of the procedure, the reference aggregate dose being obtained by taking into account anatomical deformations applied to the organs, so as to determine a reference dose actually received at each treatment session by the organs, as a function of their actual shape and/or actual position during this session.
