| Outline of Final Research Achievements |
In recent years, MRI that is a digital tomography technique using magnetic resonance has been actively studied. The resolution of MRI depends on the magnetic field strength; to achieve high resolution is required high magnetic field. This is because MR data analyzed by the FFT. Accordingly, we have focused on the NHA which can be analyzed with a high accuracy than the FFT, and verified visualization of microscopic regions that could not be observed until now in this study.
As a result, when assume an ultra-low magnetic field by computer simulation, it found that NHA can be suppressed the variation of the position error than FFT to 1/2 or less.
