The science behind ultrasound technology dates as far back as Pythagoras in the 6th century BC who wrote about the mathematical properties of stringed instruments and the harmonic scales. Since then, acoustics, the science of sound, has made incredible advances in the various applications of sound and frequency with regard to medical technology. Two of the most recent advances with acoustics occurred during the 20th century with the advent of therapeutic ultrasound and medical ultrasonography, both having revolutionary implications in the areas of medicine and technology.

Therapeutic ultrasound has many applications, with a long history of use. Beginning in the 1940’s, its uses in human imaging have added a significant contribution to the field, having a well-accepted history of use. The basic premise of Therapeutic ultrasound rests with the principle that different sound frequencies possess certain capabilities beyond the normal hearing range of humans. In 1774, Lazzaro Spallanzani observed the fact that bats navigated using sound, not eyes. A hundred years later, in 1893 Francis Galton released a novel invention allowing him to produce ultrasound, that is, a device which allowed him to measure the sound range of humans and animals. Today it is used for imaging of the human body. Application of sounds emitted beyond the normal human hearing range to produce visual images is the principle behind modern-day Ultrasound technologies. Today Therapeutic uses have expanded to include using sound frequencies for breaking down scar tissue and achieving phonophoresis. phonophoresis is a non-invasive technique for administering medications blow the skin, removing the need for injections. Conditions like tendonitis have also been effectively treated using ultrasound frequencies.

One of the primary uses of ultrasound mesa az technology is human imaging, or, medical ultrasonography. Mothers who want to see images of their unborn child before birth go to medical imaging centers that use medical sonography, or frequencies used to produce images. Frequencies of (7-18Mhz) produce images of superficial structures like muscles, tendons, testes, breast, even the neonatal brain. Deeper structures like the kidney are imaged best at a lower frequency between 1-6 Mhz. Many separate branches of medical ultrasonography have arisen based on the imaging properties of sound and the various types of organs doctors can see based on the frequency range used. Obstetrical sonography is a form of medical sonography using sound frequency to produce prenatal images. Most obstetrical sonography is performed for mothers who are between 18 and 20 weeks to confirm the baby is healthy. Although many mothers use this type of sonography for keepsake purposes, it has the potential to provide doctors with valuable information with regard to any possible medical conditions the child may have, including physical abnormalities. As a matter of fact, the most common form of sonography used there is Obstetrical sonography.

In retrospect, ultrasound technologies have grown to include a wide range of uses. These provide medical professionals in various branches with the capability of using sound frequencies for therapeutic and diagnostic purposes. Over the last several decades, it has become an essential part of our everyday life.
