摘要: Computer Assisted Surgery (CAS) is a new navigation support for skull base surgeons. The combination of 3D coordinate measurement techniques, voxel processing methods and pseudo-3D image presentation supports preoperative planning therapy, pathfinding during the operation itself postoperative therapy control. For this purpose, surgeon employs hand-guided electro-mechanical digitizer to locate points interest within operative field. coordinates measured way are correlated with model object gained by preceding CT examination. With prototype system accuracy method has proven be better than ±1 mm. been successfully applied in more 100 ENT operations ten neurosurgical procedures. A similiar was tested two times field radiotherapy computer assisted placement afterloading probes.
