A Novel Augmented Reality-Based Navigation System in Perforator Flap Transplantation - A Feasibility Study.

摘要: BACKGROUND In perforator flap transplantation, dissection of the is an important but difficult procedure because high variability in vascular anatomy. Preoperative imaging techniques could provide substantial information about anatomy; however, it cannot direct guidance for surgeons during operation. this study, a navigation system (NS) was established to overlie map on surgical sites further guide transplantation. METHODS The NS based computed tomographic angiography and augmented reality techniques. A virtual reconstructed according data projected onto real patient images using ARToolKit software. Additionally, screw-fixation marker holder created facilitate registration. With use tracking display system, we conducted animal model measured error rapid prototyping model. RESULTS assistance allowed correct identification, as well safe precise perforator. mean value determined be 3.474 ± 1.546 mm. CONCLUSIONS Augmented reality-based can by directly displaying 3-dimensional individual anatomical operative field time. It will allow identification free transplantation surgery.
