Abstract
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.
