The present invention provides systems and methods for guiding a surgical instrument (212) into a preselected spatial relationship with a lesion (234), in particular a lesion of the breast. In an exemplary embodiment, the system includes a data translation system that translates a set of data points representing the position of the lesion into a set of three-dimensional coordinates. It also includes a tracking system that tracks the position of a surgical instrument in three-dimensional space, and further includes a representation system that produces a representation (242, 244) of the position of the surgical instrument relative to the lesion. The systems of the present invention are correlated with methods for biopsy of a lesion and for surgically removing a lesion.

La présente invention concerne des systèmes et des procédés qui permettent de guider un instrument (212) chirurgical dans une relation spatiale présélectionnée avec une lésion (234), en particulier une lésion du sein. Dans un mode de réalisation exemplaire, le système de l'invention comprend : un système de traduction de données qui traduit un ensemble de points de données représentant la position de la lésion en un ensemble de coordonnées tridimensionnelles; un système de localisation qui localise la position d'un instrument chirurgical dans un espace tridimensionnel; et un système de représentation qui produit une représentation (242, 244) de la position de l'instrument chirurgical par rapport à la lésion. Les systèmes de l'invention sont associés à des procédés permettant d'effectuer la biopsie d'une lésion et d'enlever celle-ci par chirurgie.
