ABSTRACT:
Noninvasive pain treatment of skeletal cancer metastases in cancer patients utilizing planar or focused ultrasound. The ultrasound energy preferably targets at the Periosteum or immediate soft-bone-tissue interface, where local sensory pain receptors are directly affected by the growing tumor, to generate heat to destroy local sensory pain receptors so as to interrupt or block the pain feedback pathway to the central nervous system.
