| Outline of Final Research Achievements |
An integrated surgical navigation system using image guidance by both MR images with a closed bore scanner and real-time ultrasound images, and a motorized manipulator for targeting was developed to assist image-guided needle insertion. A GE 1.5 T scanner and a Siemens 3T scanner were used. After 3D MR image acquisition, patient table was pulled out. A motorized manipulator with an optical tracking system automatically chased the target point without a time-consuming registration process using surface markers. A surgeon could insert a needle while monitoring both real-time ultrasound images and reformatted MR images in the corresponding image plane. This system was applied to the animal experiment using rabbits.
