(EN) RADIATION THERAPY TREATMENT PLANNING
(FR) PLANIFICATION DE TRAITEMENT DE RADIOTHÉRAPIE
Abstract
(EN) A method and apparatus for generating a radiation treatment plan for a volume comprising: receiving a first treatment plan upon which to base a second treatment plan, the first treatment plan indicative of a dose distribution; receiving at least one dose-distribution-derived function configured to provide a value based on at least part of the dose distribution; receiving a target for the respective value of each dose-distribution-derived function comprising receiving a probability distribution; determining an optimization problem, wherein the or each objective function is a function of the dose-distribution-derived function, the respective probability distribution and a respective loss function; performing the optimization process based on said optimization problem; and determining said second treatment plan.
