摘要

Stereoscopic radiography has been used routinely at the Montreal Neurological Institute for many years. Recently, with the advent of stereoscopic acquisition and display techniques for digital angiography, together with the increased use of 3-D display techniques for medical images, we have developed and implemented a stereoscopic display workstation for use in a clinical context. The system is based on standard AT-bus computer hardware and includes a high performance monitor equipped with a liquid-crystal polarizing shutter to display the stereoscopic images. The most significant application of this system has been planning for the stereotactic implantation of EEG recording electrodes. Here the surgeon has the ability not only to view the imaged anatomy in three-dimensions, but he is also able to interact with the images and to plan surgical procedures in a more realistic manner than traditional 2-D approaches. Display modes include vascular anatomy (from stereoscopic digital subtraction or MR angiography), or a combination of DSA images and 3-D volume-rendered MR or CT reconstructions.
