A SIMPLE METHOD OF PHASE UNWRAPPING FOR NMR IMAGES

Jiří P.ibil – Ivan Frollo

   The goal of the paper is a new method for smoothing of nuclear magnetic resonance (NMR) phase images measured by the gradient echo (GE) sequence method. The magnetic filed inhomogeneity is coded in a phase image that is outwardly demonstrated by phase jumps. For a practical study and detection of the magnetic field inhomogeneity, the unwrapping of absolute phase jumps greater than 2π must be processed in the first instance.
