| Outline of Final Research Achievements |
The magnetic resonance system (MR system) is a powerful tool in the clinical filed. Images with higher sensitivity, higher resolution and higher contrast can be achieved at higher static magnetic field strength. However, non-uniformity of image is caused due to inhomogeneous radio frequency magnetic field distribution. In this research, we proposed a non-uniformity correction method to overcome this problem and developed the techniques that are required for correction of the whole human brain image. We previously develpoed the ratio map method for a single silce correction. In this work, we improved this method and applied it to multiple slice correction.
