Live endoscopic video streams augmented for 3D-navigation

摘要: Endoscopic and video-endoscopic procedures in ENT neurosurgical interventions are ideally apt for navigation. 3D-Navigation with endoscopy satisfies the surgical demand of precise information regarding localization instruments patient’s anatomy. We provide a solution augmenting performance acceptance: 3D-navigated (video-)endoscope armed Laser, providing non-contact image-processing-based position-sensing. It is paradigmatically implemented functional endoscopic sinus surgery (FESS) ORL-surgery. Basically, Laser beam crosses field-of-view hits an anatomical structure. With known calibrated geometry Naviscope spot live video stream can be extracted to yield spatial distance patient relative distal tip endoscope along optical axis, 0° (R. Wolf, Germany). This displayed easily navigation system. For angled scopes straightforward analysis required implementing The positional combined appropriate FRE/TRE methodology stochastic predictor clinical application accuracy. position reflecting estimated accuracy variety means like proportional 3D-broadening calculated cross-hair preoperative data sets that show spot’s locus. Thus “smeared” navigated tool set instruct surgeon about reliability navigational intuitive way. whole system IGSTK-based runs tracker.
