治療計画と複数ナビゲーションの統合によるMRI誘導下穿刺術の精度向上

抄録

We have developed a real-time MR image-guided surgical support system. To assist the operation-guide imaging anddisplay technique, we developed an image controller by integrating an improved two-dimensional real-time image-guide
(Interactive Scan Control: ISC), a three-dimensional high-resolution image-guide (3D-navigation) and an image fusiontechnique (Augmented reality-navigation) that has improved the function of displaying segmented images of individualorgans. Moreover, an additional preoperative planning function has been prototyped, which perioperatively displayspositional information of access path calculated on three-dimensional MRI images using the three-dimensionalhigh-resolution image-guide.
Application of this system to an in-vivo experiment confirmed the operator to easily puncture the target with these fourfunctions.
