Sonography, also known as ultrasonography or ultrasound, is the use of high frequency sound waves to build images of body organs and blood vessels. The images enable medical doctors and other medical professionals to observe, study and diagnose growth and other changes that may occur within an individual’s body. A sonographer is a professional highly trained in the use of sonography to construct the images needed.
Sonographers are probably best known for providing those first images many expecting parents see of their unborn babies. But the job of a sonographer doesn’t end there. They play an important role in helping physicians diagnose and monitor a variety of medical conditions that otherwise cannot be seen.
Sonographers use advanced sound-wave technology to create images of the body’s internal structures or organs. A sonographer’s job is to capture the best two-dimensional images possible of three-dimensional organs to be examined by physicians to assess and diagnose the patient. To do this, they must have a strong understanding of human anatomy and their sonography equipment to acquire useful images that will allow the physician to make the best diagnosis.
