Focused ultrasound

Focused ultrasound

Focused ultrasound (FUS) is a non-invasive, image-guided surgical technology that uses ultrasound energy to target specific areas of the brain and body in the treatment, or investigation of safety and efficacy in a number of indications including; essential tremor, brain cancer, Alzheimer’s disease, severe depression, and Parkinson’s disease. It is considered to be scalpel-free, avoiding incisions to the skin. Sunnybrook is a global leader in FUS research and clinical trials, and the first Centre in Canada to be recognized as a Centre of Excellence in Focused Ultrasound.
