A novel model-predictive controller that leverages Magnetic Resonance Temperature Imaging to guide High Intensity Focused Ultrasound (HIFU) cancer therapies has been implemented and tested in vivo. The controller reduces treatment time by optimizing individual pulse heating and cooling times while guaranteeing treatment safety. The clinician retains full supervisory control while leveraging a computer's ability to rapidly monitor and adjust many parameters simultaneously.
