Title
(EN) METHODS AND SYSTEMS USING MODELING OF CRYSTALLINE MATERIALS FOR SPOT PLACEMENT FOR RADIATION THERAPY
(FR) PROCÉDÉS ET SYSTÈMES UTILISANT LA MODÉLISATION DE MATÉRIAUX CRISTALLINS POUR UN PLACEMENT DE POINT POUR UNE RADIOTHÉRAPIE
Abstract
(EN) A crystalline structure modeling methodology that is conventionally used to model crystalline matter down to the atomic level is instead used to determine spot placement for radiation treatment. The cross-sectional shape of a treatment target is specified 202; locations (peaks) in a density field inside the shape are determined using the crystalline structure model 204; locations of spots in the treatment target for spot scanning are determined 206, where the locations correspond to the locations (peaks) inside the shape determined using the crystalline structure model; and the locations of the spots are stored as candidates for potential inclusion in a radiation treatment plan 208.
(FR) Selon la présente invention, une méthodologie de modélisation de structure cristalline qui est conventionnellement utilisée pour modéliser une matière cristalline jusqu’au niveau atomique est utilisée pour déterminer un placement de point pour un traitement par rayonnement. La forme de section transversale d’une cible de traitement est spécifiée 202 ; des emplacements (pics) dans un champ de densité à l’intérieur de la forme sont déterminés au moyen du modèle de structure cristalline 204 ; des emplacements de points dans la cible de traitement pour un balayage de point sont déterminés 206, les emplacements correspondant aux emplacements (pics) à l’intérieur de la forme déterminée au moyen du modèle de structure cristalline ; et les emplacements des points sont stockés en tant que candidats pour inclusion potentielle dans un plan de traitement par rayonnement 208.
