摘要：

Computer-assisted surgery (CAS) is a new navigation aid for skull-base surgeons. The combination of 3D coordinate measurement techniques, voxel processing methods, and pseudo-3D image presentation supports preoperative planning of therapy, path-finding during the operation itself, and postoperative therapy control. For this purpose the surgeon employs a hand-guided electromechanical 3D-coordinate digitizer to locate points of interest within the operative field. The coordinates measured this way are correlated with a voxel model of the object gained by a preceding CT examination. With a prototype system the accuracy of this method has proven to be better than it mm. The system has been successfully applied in more than 60 ear-nose-throat (ENT) operations and four neurosurgical procedures. © 1990 IEEE
