A system for indicating a location within a body of a patient comprises: a reference contour (394) having a position in fixed relation to the body for providing reference points; means (320, 324) for generating images of the body, said images including reference images corresponding to the reference contour; reference means (300) having a location outside the body for providing a reference; a surgical probe (302) including a tip (301, 541) having a position; first means (360) for determining the position of the tip of the surgical probe relative to the reference means; second means (306) for determining the position of the reference contour of the body relative to the reference means so that the position of the tip relative to the reference contour of the body is a known position; means (314) for translating the known position of the surgical probe to provide a translated position within a coordinate system corresponding to the images of the body; and means (326) for displaying an image of the body to provide a displayed image that corresponds to the translated position of the tip of the surgical probe. <IMAGE> |
