Fast automatic linear off-resonance correction method for spiral imaging |
摘要 |
A fast automatic linear off-resonance correction method for MRI data uses a set of widely spaced demodulation frequencies to estimate a low-resolution field map from the image itself. A linear map is determined by fitting to this low-resolution map using a maximum-likelihood estimator with weights proportional to the pixel intensity.
