Ultrasonography Nursing Career Resources

Ultrasonography is a technique in which high-frequency sound waves are bounced off internal organs and the echo pattern is converted into a 2 dimensional picture of the structures beneath the transducer. Ultrasonography embraces several procedures that aid in diagnosing ailments. Besides the familiar x ray, another common diagnostic imaging method is magnetic resonance imaging (MRI), which uses giant magnets that create radio waves, rather than radiation, to form an image. Not all imaging technologies use ionizing radiation or radio waves, however. Sonography, or ultrasonography, is the use of sound waves to generate an image for the assessment and diagnosis of various medical conditions. Many people associate sonography with obstetrics and the viewing of the fetus in the womb, but this technology has many other applications in the diagnosis and treatment of medical conditions.

Ultrasonographers, also known as, Diagnostic medical sonographers, use special equipment to direct nonionizing, high frequency sound waves into areas of the patient’s body. Sonographers operate the equipment, which collects reflected echoes and forms an image that may be videotaped, transmitted, or photographed for interpretation and diagnosis by a physician.
Sonographers begin by explaining the procedure to the patient and recording any medical history that may be relevant to the condition being viewed. They then select appropriate equipment settings and direct the patient to move into positions that will provide the best view. To perform the exam, sonographers use a transducer, which transmits sound waves in a cone- or rectangle-shaped beam. Although techniques vary with the area being examined, sonographers usually spread a special gel on the skin to aid the transmission of sound waves.
