Abstract[English]
Disclosed is a computer-implemented method of planning a straight trajectory in a medical image of an anatomical structure. A template of the straight trajectory is given in an atlas and the atlas is registered with the medical image. The atlas is divided into a first area and one or more second areas, wherein the first area comprises the straight trajectory and the one or more second areas do not comprise any part of the straight trajectory. When the transformation of the atlas onto the medical image is calculated, the first and second areas are treated differently. The transformation of the first area maintains the straight shape of the trajectory and is thus restricted. The transformation of the one or more second areas is unrestricted and thus allows any kind of image registration. The template of the transformed atlas is the applied to the medical image.[French]
La présente invention divulgue un procédé mis en œuvre par ordinateur de planification d'une trajectoire droite dans une image médicale d'une structure anatomique. Un modèle de la trajectoire droite est donné dans un atlas et l'atlas est enregistré avec l'image médicale. L'atlas est divisé en une première zone et une ou plusieurs secondes zones, la première zone comprenant la trajectoire droite et la ou les secondes zones ne comprenant aucune partie de la trajectoire droite. Lorsque la transformation de l'atlas sur l'image médicale est calculée, les première et seconde zones sont traitées différemment. La transformation de la première zone garde la forme droite de la trajectoire et est ainsi limitée. La transformation de la ou des secondes zones n'est pas limitée et permet donc tout type d'enregistrement d'image. Le modèle de l'atlas transformé est appliqué à l'image médicale.
