Fetus monitoring in which prenatal images are obtained in order to monitor the fetusās progress.

Echocadiography, which permits physicians to observe heart valves functioning. This entails the insertion of a emitting/receiving ultrasonic transducer (operating in the 4 MHz range) down the patientās esophagus to a point directly behind the region of interest in the heart. The transducer emits a signal which is reflect back to be detected by the selfsame transducer.

 

Blood vessel monitoring is rendered possible by extreme miniaturization of the transducers and the use of techniques of cardiovascular probes.

 

Kidney stone disintegration is rendered possible by the fact that small particles can break when subject to resonant or critical frequencies.

Dental plaque is removed by a narrow high-speed stream of water under the impetus of (generally) 25 kHz signal introduced into the stream.

Since the molecular relaxation processes result in heat generation in a solid, liquid or semi-liquid medium, ultrasound can be applied to affected areas to ease muscular soreness.

Ultrasonic cleaners are used to clean operating tools and other utensils. The acoustic energy is generally transmitted into a detergent fluid in which the utensils are submerged.

Current research at the New York University Medical Center indicate a great deal of promise in the use of ultrasound to treat skin cancer.

Clinical studies are being conducted in the use of ultrasound to unclog blood vessels affected by arteriosclerosis.
