Abstract

The disclosure is directed to a method and apparatus for presenting a plurality of scanning images in a video presentation. The disclosure is particularly directed to the use of such an apparatus and method in stereotactic surgery, wherein acquisition of a plurality of scanner images, conversion of these images into a selected standard format, storage of the acquired and converted images, selective recall and display of at least two of the images, and independent manipulation of each of the images for comparision are provided. Probe placement can be simulated and the images can be enhanced in various ways. The images used can be, for example, CT, PET, X-ray, DSA, isotope, and NMR scans. Brain map atlas images can be superimposed on and fitted to the scan images of a particular brain. Video displays of three dimensional simulations can also be produced.
