The problem of providing surgical navigation using image overlays on the operative scene can be split into four main tasks -calibration of the optical system; registration of preoperative images to the patient; tracking of the display system and patient and display using a suitable visualisation scheme. To achieve a convincing result in the magnified view through the operating microscope high alignment accuracy is required. We have simulated our entire system to establish the major sources of<span class="external-identifiers"> <a target="_blank" rel="external noopener noreferrer" href="https://doi.org/10.1007/10704282_91">doi:10.1007/10704282_91</a> <a target="_blank" rel="external noopener" href="https://fatcat.wiki/release/yjmmlwxpajhfllsetpxtanhohu">fatcat:yjmmlwxpajhfllsetpxtanhohu</a> </span>

We have introduced bone-implanted markers for registration and incorporated a locking acrylic dental stent (LADS) for patient tracking and/or registration. These improvements have significantly increased the alignment accuracy of our overlays. LADS repositioning on volunteers showed a mean target registration error of 0.7mm. Phantom accuracy is 0.3-0.5mm and clinical overlay errors were 0.5-1.0mm on the bone fiducials and 0.5-4mm on target structures. We have improved the graphical representation of the stereo overlays. The resulting system provides 3D surgical navigation for microscope-assisted guided interventions (MAGI). C. Taylor, A. Colchester (Eds.): MICCAI'99
