Proton resonance frequency (PRF) shift-based MR thermometry provides a non-invasive temperature mapping method for monitoring the progress of RF ablation therapies. Multi-baseline and referenceless methods have been used to address the complications caused by motion in standard PRF method. In this work, we present a computationally efficient and simplified real-time hybrid (multi-baseline + referenceless) MR thermometry technique for monitoring MR-guided thermal therapies.
