A displacement of a lesion within a patient is determined for the purpose of administering radiation treatment by generating sets of surface elements from three-dimensional images of the lesion taken at different times. Weights are assigned to the surface elements, and based on weights and the proximity of corresponding elements in one set to elements in another set, a displacement is determined.

Un déplacement d'une lésion chez un patient est déterminée en vue d'un traitement par radiothérapie, en générant des ensembles d'éléments de surface à partir d'images tridimensionnelles de la lésion prises à des moments différents. Des charges sont assignées aux éléments de surface et, sur la base de ces charges et de la proximité des éléments correspondants d'un ensemble d'éléments à l'autre, un déplacement est déterminé.
