Billy T: You're thinking of lithotripters for kidney stoneys, etc. Focused-ultrasound focuses ultrasound (duh!) to a single point, raising the temperature at that point about 2 degrees C/second in human tissue, essentially cooking the offending tissue (cancer, fibroid, etc.) in about 20 seconds. Multiple treatments can eliminate uterine fibroids in about 45 minutes, with no discomfort to the patient. Now, back to the Universe!
