1. A method of ultrasonically cutting off the blood supply to a uterine fibroid without necrosing the entire fibroid, comprising the following steps of:

  • a) providing an ultrasonic transducer configured to emit focused high intensity ultrasound energy;

    b) pre-selecting one or more tissue treatment sites located on the uterine fibroid wherein the one or more tissue treatment sites are selected such that necrosing the tissues at the one or more tissue treatment sites will decrease the blood supply to the uterine fibroid; and

    c) applying the ultrasound energy to only the pre-selected tissue treatment sites.
