  • Ultrasound

    A form of acoustic energy, or sound, that has a frequency that is higher than the level of human hearing. As a medical diagnostic technique, high frequency sound waves are used to provide real-time medical imaging image inside the body without exposure to ionizing radiation. As a therapeutic technique, high frequency sound waves interact with tissues to destroy diseased tissue such as tumors, or to modify tissues, or target drugs to specific locations in the body.
