Purpose: The purpose of this study was to develop and verify an intraoperative module for supporting navigated biopsy procedures using optical see-through head-mounted display (HMD). Methods: Biopsy procedure including entry endpoints needle insertion planned preoperatively having regard the resection region segmentation safety margin definition. were performed by two users navigation on a specially prepared brain phantom. Two visualization techniques compared: accurate augmented reality one, where virtual plan is superimposed onto surgical field HMD together with personalized calibration method external display. Results: Averaged errors from 24 trials 2.04 ± 0.83 mm first user 2.69 1.11 second while applying 2.50 0.93 (the user) 2.17 0.82 user), respectively. Conclusions: Proper usage preceded allows perform comparable accuracy its equivalent Additionally, improves ergonomics enables focusing without losing direct line sight view as it happens displays. However, ensuring high still requires proper some experience, which challenging.
