English-born physicist John Wild (1914â2009) first used ultrasound to assess the thickness of bowel tissue as early as 1949; he has been described as the father of medical ultrasound. Subsequent advances in the field took place concurrently in several countries.
Ultrasound is safe and painless, and produces pictures of the inside of the body using sound waves. Ultrasound imaging, also called ultrasound scanning or sonography, involves the use of a small transducer (probe) and ultrasound gel placed directly on the skin.High-frequency sound waves are transmitted from the probe through the gel into the body.ltrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Conventional ultrasound displays the images in thin, flat sections of the body. Advancements in ultrasound technology include three-dimensional (3-D) ultrasound that formats the sound wave data into 3-D images.
