Ultrasound imaging
Ultrasound Imaging
Ultrasound imaging, also known as sonography, is a medical imaging technique that uses high-frequency sound waves to visualize the internal structures of the body.
Pronunciation
Ultrasound imaging: /ˈʌltrəˌsaʊnd ˈɪmɪdʒɪŋ/
Etymology
The term "ultrasound" originates from the Latin words "ultra" meaning beyond, and "sound". The term "sonography" comes from the Greek words "sonos" (sound) and "graph" (to write).
Description
Ultrasound imaging is a non-invasive diagnostic procedure that captures images of the body's internal structures. It is commonly used in medicine to visualize fetuses during pregnancy, and to examine the heart, blood vessels, kidneys, liver, and other organs.
The procedure involves the use of a small transducer (probe) and ultrasound gel placed directly on the skin. High-frequency sound waves travel from the probe through the gel into the body. The probe collects the sounds that bounce back. A computer uses those sound waves to create an image.
