SURG-37. NEURO-ONCOLOGICAL AUGMENTED REALITY: A MORE INTUITIVE APPROACH TO RESECTION PLANNING

Abstract BACKGROUND When preparing for the resection of an intracranial lesion, its borders and optimal approach are often determined using neuronavigation with a tracked pointer. This can sometimes prove challenging, especially deep-seated lesions. Augmented reality (AR) simplify improve this step by directly displaying lesion on patient's skin. METHODS A proprietary inside-out infrared tracking solution was developed, allowing heads-up AR scenes Microsoft HoloLens II without need external camera or computer. We included twenty patients intracerebral planned resection. After semi-automatic hologram-to-patient registration, different participants marked outlines patient’s skin, consecutively aided Brainlab system HoloLens. Each registration both systems provided transform that compared accuracy consistency. Participant performance quantified in terms duration patient delineation, to expert performance. RESULTS delineation were significantly faster than conventional (p = 0.02 p < 0.001, respectively, 0.001 total duration), taking 79.23 ± 17.48 39.58 39.10 seconds while required 96.61 24.54 90.80 44.09 seconds. had offset 3.3mm 3.4°, more consistent neuronavigation. facilitated accurate detailed overestimated size. CONCLUSION provides alternative planning. Lesion intuitive retaining high accuracy. Future research should focus further intraoperative implementations.
