Ultrasound uses acoustic vibrations that penetrate into deeper layers of the tissues, breaking down scar tissue, reduces swelling, and aids in reducing calcified spurs.
Ultrasound is a non-invasive diagnostic technique used to image inside the body. Ultrasoundprobes, called transducers, produce sound waves that have frequencies above the threshold of human hearing (above 20KHz), but most transducers in current use operate at much higher frequencies (in the megahertz (MHz) range). Most diagnostic ultrasound probes are placed on the skin. However, to optimize image quality, probes may be placed inside the body via the gastrointestinal tract, vagina, or blood vessels. In addition, ultrasound is sometimes used during surgery by placing a sterile probe into the area being operated on.
