Magnetic resonance imaging apparatus and magnetic resonance image data processing method |
摘要 |
A magnetic resonance imaging apparatus 20 includes a phase difference calculation unit 44 configured to perform a one-dimensional Fourier transform on complex data not phase-encoded extracted from complex data of a nuclear resonant signal collected by dynamic scanning, and determining a phase difference in time of data obtained by performing a one-dimensional Fourier transform on the complex data not phase-encoded, and a correction unit 50, 51 configured to correct for a non-uniformity of static magnetic field caused during the dynamic scanning, depending upon the phase difference.
