Ultrasound Machines in Modern Medicine

Ultrasound is a word that is used to describe sound that on such a high frequency that the human ear cannot hear it. In general, the lowest frequency at which ultrasound can be done is 20 KHz, because anything below this frequency is audible to the human ear, which is known as infra-sound.

Ultrasound machines use a transducer, which emits ultrasound waves and detects their echoes, then transmits this information to a computer monitor. From there, the echoing sound waves are transformed into images, allowing doctors to see organs or a human fetus with clarity. The benefit of using ultrasound is that it has no known harmful effects to the human body and uses no radiation, making it much safer form of diagnostic technology than x-rays.

In the world of medicine, ultrasound machines have many applications, but the most common one is collecting information about the fetus during pregnancy. Depending on the type of ultrasound machine and where it is used on the body, it can be used to treat many different types of health problems.

Ultrasound can detect abnormalities in the heart, organs and other parts of the body. Ultrasound surgery can be used to treat tumors by focusing a highly intense ultrasound wave at specific frequencies. It can deliver highly penetrable chemotherapy medication to brain cells for treatment of brain cancer. Ultrasound can also administer physiotherapy; treatment of cataracts and even for teeth cleaning. Ultrasound is also used in many forms of diagnostic treatment, but most commonly for viewing a woman’s uterus and the fetus during pregnancy.

Thanks to recent advances in ultrasound technology, doctors expect to be using ultrasound machines more and more as a way to treat patients.
