Abstract

The advances in radiographic imaging techniques that have occurred within the past decades have significantly enhanced our abilities to display anatomy as well as pathology. Although image acquisition commonly generates three-dimensional datasets, limitation in user interfaces generally requires that this information be presented clinically as a series of two dimensional images. Consequently, during preoperative planning, surgeons are required to mentally transform a wealth of two dimensional hard copy images qualitatively into three-dimensional concepts that are used as a road map to surgery. The sugeron's success is dependent on the accurate mental transfer of Computer Tomographic X-ray (CT) and Magnetic Resonance (MR) imaging information to the operative site to assist direct visual perception of the procedure. Thus, the surgical procedure is performed with the surgeon intuitively transferring radiographic information to the surgical site. Neurosurgeons, for example, are especially hampered because of limited ability to visually distinguish tumor tissue, peritumoral edema, and normal brain parenchyma. This limitation at least partially accounts for the relatively high incidence of subtotal tumor excision. Based on the need to assit the surgeon transform the preoperative scans to the operative site, stereotactic systems were developed and would evolve into frameless stereotaxy with the advance of various sensors.
