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.
In general, ultrasounds (or sonograms) are technically used in medicine to detect changes in appearance of organs, tissues, and vessels or to detect abnormal masses. Most people think of them as what pregnant women get to see the fetus inside their body. However, they have many, many other important uses. Ultrasound scanning is noninvasive and is usually painless. It is widely available, easy-to-use and less expensive than other imaging methods. It can be a safer option since it does not use any x-ray radiation and provides a clear picture of soft tissues that do not show up well on x-ray images. Ultrasounds can provide real-time imaging. Physicians may use ultrasound as a diagnostic tool but itâs not limited to diagnosis.
