Abstract
The results of an open magnetic resonance (MR) imaging-based navigation system for a breast-conserving surgery were presented. This real-time 3D virtual reality navigation system with open MRI is feasible for safe and accurate excision of nonpalpable MRI-detected breast tumors. We have also developed a real-time augmented reality navigation system utilizing the open MRI, and used as many MR-incompatible surgical instruments as possible out of 5G restriction area. Although we used many MR incompatible surgical instruments, 6 laparoscopic operations were completed safely and neither intraoperative complication nor other difficulties occurred. During the operations, the laparoscopic monitor clearly showed the augmented reality models of the intraperitoneal structures such as the common bile duct, the urinary bladder, or the proper position of the prosthesis. Laparoscopic surgery with our developed real-time augmented reality navigation system in the open MRI therapeutic room is so far feasible and effective.
