• E-3 An Augmented Reality Navigation System for Open type MRI with LCD Slice Image Overlay device

抄録

Currently, MRI is used not only for diagnosis but also for intraoperative surgical treatment. The surgeon determines the position of the disease region by comparing the MR image and the patient's condition during the operation. Therefore, the predicted spatial position of the diseased part is based mainly on the surgeon's knowledge and experience, and surgeons do not fully utilize the information obtained from the MR image. In order to provide intuitive visualization of MR image for surgery navigation, we developed LCD slice image overlay navigation system that augments MR image onto patient's body. Phantom experiments have been performed to evaluate image overlay accuracy of the system. The result of a target registration error of 1.4 ± 0.6 mm. It has been shown that the proposed system can function as a new vision system for open-type MRI systems and assist surgeons in minimally invasive surgeries.
