Title
(EN) ASSESSING TREATMENT PARAMETERS FOR RADIATION TREATMENT PLANNING
(FR) ÉVALUATION DE PARAMÈTRES DE TRAITEMENT POUR LA PLANIFICATION D'UNE RADIOTHÉRAPIE
Abstract
(EN) Information associated with a radiation treatment plan includes, for example, values of dose per voxel in a target volume, values of dose rate per voxel in the target volume, and values of parameters used when generating the values of dose per voxel and the values of dose rate per voxel. Renderings that include, for example, a rendering 504 of an image 514 of or including the target volume, and a rendering 502 of selected values of the radiation treatment plan, are displayed. When a selection of a region of one of the renderings is received, a displayed characteristic of another one of the renderings is changed based on the selection.
(FR) Des informations associées à un plan de radiothérapie comprennent, par exemple, des valeurs de dose par voxel dans un volume cible, des valeurs de débit de dose par voxel dans le volume cible, et des valeurs de paramètres utilisés lors de la génération des valeurs de dose par voxel et des valeurs de débit de dose par voxel. Des rendus qui comprennent, par exemple, un rendu 504 d'une image 514 du volume cible ou le comprenant, et un rendu 502 de valeurs sélectionnées du plan de radiothérapie, sont présentés. Lorsqu'une sélection d'une région de l'un des rendus est reçue, une caractéristique présentée d'un autre des rendus est modifiée sur la base de la sélection.
