• An ultrasound technologist, also known as a sonographer, uses an ultrasound machine that emits sound waves through a patient's body to analyze internal organs. Most commonly known for performing ultrasounds on pregnant women, sonographers image all parts of the body. The sonographer takes the images, consults with the physician and interprets the images into preliminary results.


    Sonographers usually obtain an associate degree or a two-year certificate from a vocational school. Some universities offer a bachelor degree in the field of ultrasound technology.

    Work Environment

    Sonographers may work in a hospital, an outpatient setting or a doctor's office. They work in dark environments and may have to work on holidays and weekends.

    Types of Sonographers

    There are several types of sonographers. Some specialize in vascular technology, echocardiography or obstetrics. Ultrasounds are used to image virtually every part of the body, so sonographers can specialize in order to be proficient, or they can work as a general sonographer who can work in any field.


    An ultrasound technologist works independently and consults with a physician as necessary. She takes the images, makes any necessary measurements and stores the images. The physician reviews the images to make a diagnosis.


    Because ultrasound does not use radiation and it is inexpensive, it is being utilized more and for a wide variety of procedures. Job growth is expected to grow faster than the national average. From 2008 through 2018, jobs should increase 18 percent, according to the Bureau of Labor Statistics.
