To evaluate the feasibility, robustness, and accuracy of a 3D image-based registration system pairing endoscopic video with intraoperative cone-beam CT for skull base surgery.
Quantified registration accuracy as a function of system geometry, computational runtime, and CBCT image quality metrics including noise and resolution.
Evaluated overall registration accuracy using a cadaver model simulating transsphenoidal skull base tumor resection.
Image-based registration achieved a mean reprojection distance error of 1.28 mm compared with 1.82 mm for conventional tracker-based navigation.
The image-based registration pipeline maintained robust performance despite degradation in CBCT image noise and resolution, confirming viability for low-dose intraoperative protocols.
