Title (EN) REMOVING GHOST MARKERS FROM A MEASURED SET OF MEDICAL MARKERS
(FR) ÉLIMINATION DE MARQUEURS FANTÔMES À PARTIR D'UN ENSEMBLE MESURÉ DE MARQUEURS MÉDICAUX
Abstract:
(EN) A method for removing ghost markers from a measured set of medical markers, wherein the measured set of markers represents the positions of real markers and the positions of ghost markers, comprising the steps of: - calculating all possible minimal marker sets, wherein a minimal marker set is a subset of the measured set and a minimal marker set consists of the smallest possible number of markers which would cause the measured set to be measured; - calculating the smallest extent of each minimal marker set, wherein the smallest extent is the smallest extent among the extents in three orthogonal directions; and - selecting the minimal marker set having the smallest out of the smallest extents as a marker set without ghost markers.
(FR) L'invention concerne un procédé d'élimination de marqueurs fantômes à partir d'un ensemble mesuré de marqueurs médicaux, l'ensemble mesuré de marqueurs représentant les positions de marqueurs réels et les positions de marqueurs fantômes, comprenant les étapes consistant à : - calculer tous les ensembles de marqueurs minimaux possibles, un ensemble de marqueurs minimal étant un sous-ensemble de l'ensemble mesuré et un ensemble de marqueurs minimal étant constitué du plus petit nombre possible de marqueurs qui amèneraient l'ensemble mesuré à être mesuré ; - calculer la plus petite étendue de chaque ensemble de marqueurs minimal, la plus petite étendue étant la plus petite étendue parmi les étendues dans trois directions orthogonales ; et - sélectionner l'ensemble de marqueurs minimal ayant la plus petite étendue parmi les plus petites étendues en tant qu'ensemble de marqueurs sans marqueurs fantômes.
