In this work, we test a newly developed fat-referenced thermometry technique during a canine prostate ablation procedure. The fat-referenced method was compared with the conventional and drift-corrected proton resonance frequency shift (PRFS) thermometry techniques. Over the 83 minute thermal monitor period, the fat-referenced method corrected for time-varying B0 field disturbances in the prostate region.
