Title
(EN) TRACKING REPRESENTATIONS OF INDICATOR BODY PARTS
(FR) SUIVI DE REPRÉSENTATIONS DE PARTIES DE CORPS D'INDICATEUR
Abstract
(EN) The present invention relates to a method for tracking image sections which represent indicator body parts of a body in a process sequence of images, wherein changes in the position of the indicator body parts are used as an indicator for changes in the position of a treatment body part of the body which is to be treated using a treatment beam, said method comprising the following steps: providing advance image data which describe an advance sequence of images representing a result of an advance analysis of the body; providing process image data which describe the process sequence of images, wherein the process sequence of images represents a result of a process analysis of the body which is performed after the advance analysis; determining, on the basis of the advance image data, sub-images which undergo similar changes in position in the advance sequence; extracting, on the basis of the process image data and the determined sub-images, image sections from the images of the process sequence which have an image content which corresponds to the image content of the determined sub-images; and tracking the extracted image sections in the process sequence.
(FR) La présente invention concerne une méthode pour suivre des sections d'image qui représentent des parties de corps d'indicateur d'un corps dans une séquence d'images d'un procédé au cours de laquelle des changements de position des parties de corps d'indicateur servent d'indicateur pour des changements de position d'une partie de corps de traitement du corps qui doit être traité à l'aide d'un faisceau de traitement. Ladite méthode comprend les étapes suivantes : fournir au préalable des données d'image qui décrivent une séquence préalable d'images représentant un résultat d'une analyse préalable du corps ; fournir des données d'image du procédé qui décrivent la séquence d'images du procédé, la séquence d'images du procédé représentant un résultat d'une analyse du corps par le procédé qui est effectuée après l'analyse préalable ; déterminer, sur la base des données d'images préalables, des sous-images qui subissent des changements de position similaires dans la séquence préalable ; extraire, sur la base des données d'images du procédé et des sous-images déterminées, des sections d'image à partir des images de la séquence du procédé qui ont un contenu d'image qui correspond au contenu d'image des sous-images déterminées ; et suivre les sections d'image extraites dans la séquence du procédé.
