Water/Fat Separated MR Thermometry

MRI thermometry enables non-invasive real-time temperature monitoring of thermal therapies, such as tumor ablation. The typical method used for thermometry quantifies the proton resonant frequency (PRF) shift with temperature, which becomes inaccurate in fatty tissues. This can cause major problems for guiding therapies in organs such as the breast and liver. This code repository implements an algorithm that can perform accurate PRF-shift thermometry in tissues containing up to 90% fat and also correct errors due to motion, respiration, and scanner drift, in a real-time compatible manner. A numerical phantom simulator is provided as a demo for the algorithm.
