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.
