AMELIORATION DE L'ENREGISTREMENT D'UNE IMAGE ANATOMIQUE AU MOYEN D'UN SYSTEME DE COORDONNEES A SUIVI DE POSITION FONDE SUR LA PROXIMITE A UN TISSU OSSEUX
A system and method for improving registration of an anatomical image witha position-tracking coordinate system based on visual proximity to bonetissue is presented. The method can comprise identifying, in athree-dimensional (3d) anatomical image of a patient organ, multipleanatomicalpoints corresponding to respective predefined locations on a skin of thepatient organ in a first coordinate system, performing initial registration ofthe first coordinate system and a second coordinate system by correlatingbetween positions in the first coordinate system and respective anatomicalpoints in the second coordinate system, viewing a position in the firstcoordinate system using a viewing device, when the position does not matcha predetermined location, marking the position and weighting the position,and refining the initial registration of the first and second coordinatesystems, by re-correlating between the positions, the marked positions andthe respective anatomical points.
