Sonography

Sonography is a diagnostic medical test that uses high-frequency sound waves also called ultrasound waves to bounce off of structures in the body and create an image. The test is often referred to simply as an ultrasound or as a sonogram.

Medical ultrasound is a diagnostic imaging technique, or therapeutic application of ultrasound. It is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs. Its aim is often to find a source of a disease or to exclude pathology.
