Endoscopy of trabecular bone for intraoperative registration

iBoneRegistration

The project iBoneRegistration explores endoscopy of trabecular bone structures (cancellous bone) for intraoperative registration in navigated bone surgery. Trabecular bone is optimally suited as features for establishing the spatial transformation between preoperative image data and the intraoperative situation thanks to the unique structural composition. This enables intraoperative registration without artificial landmarks or additional intraoperative radiation-intensive imaging as commonly used nowadays. iBoneRegistration investigates: (1) Endoscopy techniques for in-situ acquisition of trabecular bone in drill holes. Imaging of trabecular bone will be achieved using three competing approaches (medical grade endoscopes, micro cameras and omnidirectional optics). (2) Fast and robust algorithms for registration based on endoscopic images of trabecular bone and preoperative medical images. (3) Clinical evaluation of trabecular bone endoscopy and registration methods exemplary for otology and orthopedics.
