What is ultrasonography?

ultrasonography is a imaging technique used very often in a medical area for the purposes of diagnostics or evaluation. It is a completely non -invasive procedure that involves the use of high -frequency sound waves to map the image of the inner structures of the body. The type of sound used, often called ultrasound , is at the frequency of two to 18 megahertz, far above the range that the human ear can detect.

ultrasonic waves are transmitted by a manual probe known as converter , which also detects the way the sound waves interact with the object displayed. This data is converted into a visual image on the screen. These images are usually not very clear to an untrained eye, so a trained physician called Sonographer must interpret the image. The exact frequency emitted by the converter is precisely checked and will depend on the part of the body that is displayed.

The best known use of ultrasonography is in obstetrics in which it is used to view the viewinga made fetus. The ultrasonography of the fetus serves for many purposes. Placing the placenta, the relative position of the child, as well as its gender and the health of its main organs, can be determined through ultrasonography. Potential complications and multiple births may also be detected, which makes ultrasonography a valuable tool during prenatal care. With the exception of any previous complications, it is typical for a routine ultrasound of the fetus when the fetus reached a gestational age of 20 weeks.

There are also many other ultrasonography applications outside obstetrics. Most body areas can be seen by ultrasound. The heart, bones, kidneys, digestive tract, muscles and nerves are just some of the organs and systems that can be observed by ultrasonography. One of the only organs that canntou these techniques are well observed by the lungs because they contain air that prevents ultrasonic waves in the passage through them.

Ultrasound value as such is not limited to diagnostics but also has some TERApeutic applications. For example, ultrasound can be used to brush teeth and to treat cataracts. It can also be used to destroy kidney stones and treatment of cancer growth. Ultrasonography has been widely used since the second part of the 20th century. Given the relative novelty of this type of medical technology, further discoveries will probably be made in relation to its usefulness for diagnosis and treatment.
