A model-based technique is proposed for
water/fat-separated multi-echo PRF-shift MR thermometry
that leverages recent advancements in water/fat
separation to achieve high-quality signal separations
while maintaining real-time-compatible compute times.
The method is validated in simulations and compared to
3-point Dixon-based temperature maps in canine prostate
temperature maps during a transurethral focused
ultrasound ablation.
