We propose a method to correct phase drift artifact from MR thermometry measurements with the use of Magnetic field monitoring (MFM). Field variations are measured with an array of MFM probes and correction maps are computed from the frequency shifts of FID signals. This method allows to have better resolution and can be used with any MR thermometry pulse sequence.
