| Outline of Final Research Achievements |
The final goal of this study is to establish an MR-endoscope system by integrating an endoscope on MRI to improve an accuracy of endoscopy and endoscopic surgeries by providing high quality MR images. In order to produce the high quality MR images, we aimed at developing a phased array antenna to detect an MR signal from inside the gastrointestinal tract. In addition, the navigation function for MR-endoscope system was improved to simplify an MR imaging set-up and display a target region for MR imaging on 3D view based on multi-slice MR images of stomach. The set-up time for MR imaging was shortened up to 40 seconds with animal experiment in vitro. And also, the MR imaging of gastric ulcer model using a single channel antenna at 1.5T MR scanner was examined with pigs, then the gastric ulcer region was visualized with high spatial resolution.
