| ABSTRACT: |
In recent years there has been a significant increase in
the number and use of stereotactic techniques for brain surgery. This has
been brought about by the development of new imaging technologies, for example,
computerized axial tomography, nuclear magnetic resonance scanning, various
radioisotope scanning techniques, and digital angiography. These imaging
techniques provide the surgeon with a method of “seeing” certain
prominent brain structures and can be used to aid the surgeon in planning
stereotactic procedures. The increased resolution afforded by CT and MR
scanning systems do not, however, allow direct identification of some brain
structures or regions. Such areas can only be inferred from these imaging
techniques. Stereotactic surgery, being primarily a procedure performed
without the aid of direct visualization, is dependent on sophisticated imaging
techniques for its accurate execution. It therefore necessarily follows
that as computer and imaging technology improve, so do the possibilities
of stereotactic surgery. This review is concerned with the use of computer-graphic
techniques in conjunction with CT, MR, angiographic and other imaging methods
for generating complex digital brain/atlas map images to better aid the
stereotactic neurosurgeon in localizing cortical and subcortical regions
and structures.
