Ultrasound imaging or Sonography uses sound waves to provide information about internal organs and soft tissue, such as the heart, liver, gallbladder, spleen, pancreas, kidneys and bladder. Ultrasound data, gathered in real-time and displayed on a computer monitor, often is used for examining a fetus in utero, studying the flow of blood through veins and arteries, and in diagnosing gallstones and prostate abnormalities.
Since ultrasound uses sound waves and their echoes, rather than x-rays, to view internal anatomy, the patient is not exposed to radiation. Ultrasound also can provide information about tumors and cysts that cannot be gathered by conventional x-ray. In most ultrasound examinations, a hand-held transducer is placed on the patient's skin. The transducer is both a transmitter and receiver, sending reflected echoes that are displayed as a two-dimensional image on a video screen.
All of WRA’s ultrasound units have 3D/4D capabilities, the highest level of available technology which allows images to be captured in three dimensions and with real-time movement. The 3D/4D utilities provide greater clarity to the physicians and technologists in more complex cases where finer detail is needed for a diagnosis.
