MR Thermometry-guided Prostate Hyperthermia with Real-time Ultrasound Beamforming and Power Control

• Feasibility of prostate hyperthermia with endorectal ultrasound applicators has been demonstrated in clinical trials
• This project presents a real-time MR thermometry-guided system for hyperthermia delivery within constrained regions with the ExAblate prostate array and validated it in phantom experiments.
• We developed real-time MR Thermometry platform to control the focus and power output of the ultrasound beam, ensuring constant and uniform heating within the region of treatment.
