A system for indicating a position of a tip of a probe which is positioned within an object on cross-sectional, scanned images of the object. The object includes reference points and the images of the object include reference images corresponding to the reference points. An array for receiving radiation emitted from the probe and from the reference points is digitized by a three dimensional digitizer to measure the position of the tip of the probe relative to the reference points of the object. A computer employing translational software translates the position of the tip of the probe into a coordinate system corresponding to the coordinate system of the cross-sectional images. A stereotactic imaging system selects the image of the object closest to the measured position of the tip of the probe and displays the selected image and a cursor representing the position of the tip of the probe on the selected images.
A system for indicating a location within a body of a patient, said system comprising: reference points means having a position in fixed relation to the body for providing reference points; means for generating images of the body, said images including reference images corresponding to the reference
A system for indicating a location within a body of a patient, said system comprising: reference points means having a position in fixed relation to the body for providing reference points; means for generating images of the body, said images including reference images corresponding to the reference points means; reference means having a location outside the body for providing a reference; a surgical probe including a tip having a position; first means for determining the position of the tip of the surgical probe relative to the reference means; second means for determining the position of the reference points means of the body relative to the reference means so that the position of the tip relative to the reference points means of the body is a known position; means for translating the known position of the tip of the surgical probe to provide a translated position within a coordinate system corresponding to the images of the body; and means for displaying an image of the body to provide a displayed image which corresponds to the translated position of the tip of the surgical probe.
