Abstract[English]
A method of creating an ion-based radiotherapy treatment plan includes a spot-weight optimization procedure arranged to create the plan involving an arc as a combination of one or more sub-arcs and possibly a static beam wherein the one or more sub-arcs either overlap or have different directions. The method includes selecting the first and second sets of energy levels together.[French]
Procédé de création d'un plan de traitement de radiothérapie à base d'ions comprenant une procédure d'optimisation de poids ponctuel agencée pour créer le plan impliquant un arc en tant que combinaison d'un ou de plusieurs sous-arcs et éventuellement d'un faisceau statique, ledit sous-arc se chevauchant ou ayant des directions différentes. Le procédé consiste à sélectionner les premier et second ensembles de niveaux d'énergie ensemble.
