A 3D Segmented EPI pulse sequence where the polarity of the read out train changes from measurement to measurement is used in conjunction with 2 point Dixon fat/water-separation and Temporally Constrained Reconstruction to achieve N/2 ghost-free fat-only and water-only images. The phase of the fat-only images is used to create a spatially varying least square second order fit to create corrected 3D temperature maps of the water in a water/oil phantom using the PRF method. The RMS error in a cooling experiment decreased from 4.0C to 2.5C over 265 seconds of cooling from 70C to 45C.
