What is sonographySonography is the use of sound waves to generate an image for the assessment and diagnosis of various medical conditions.  These images are used by doctors to diagnose possible problems. 

Sonography is also known as  Ultrasound Imaging or Ultrasonography.  These  high frequency sound waves (ultrasound) produce visual images of organs, tissues, or blood flow. 

What does a sonographer do?  Sonographers are also called Diagnostic Medical Sonographers or ultrasound technicians.  A sonographer description includes operating sophisticated equipment that use sound waves to generate images.  Sonography is radiation free and can be used to examine many parts of the body and aid in detecting heart  and vascular disease.

Sonographers are trained to use these images to discriminate between healthy and diseased areas. They bring to a physician's attention any suspected abnormalities. These images are used  by doctors to assess and diagnose various medical conditions. Its most well known use is in pregnancy but it is also applied to abdominal, vascular, cardiac and other imaging. A vascular sonographer performs arterial and venous diagnostic procedures using ultrasound.  A cardiac sonographer uses ultrasound to examine heart chambers, valves, and vessels.

One of the main sonographer duties is to direct nonionizing, high frequency sound waves into areas of the patient’s body.  Sonographers operate the equipment, which collects reflected echoes and forms  images that are interpreted for use in diagnosis by a physician.

Additional sonographer duties are:

  •     obtaining the patient history
  •     selecting the appropriate equipment settings
  •     positioning the patient correctly
  •     keeping patient records and prepare work schedules
  •     maintaining ultrasound equipment
  •     providing a summary of findings to the physician
  •     analyzing technical information
