| Outline of Final Research Achievements |
A phantom to correct geometric distortion and intensity inhomogeneity in magnetic resonance imaging was developed for precise evaluation of human brain volume. To make the correction system publicly available, an open source automatic phantom image analysis program was also developed and validated among the MR machines with various magnetic field strength. The method will be examined for its effect in the diagnosis of dementia in future study.
