What is ultrasound?
When used in an ultrasound scanner, the transducer sends out a beam of sound waves into the body. The sound waves are reflected back to the transducer by boundaries between tissues in the path of the beam (e.g. the boundary between fluid and soft tissue or tissue and bone)ultrasonic sound waves are the types of sound waves, which our ears are not capable of hearing.Their frequency is more than 20000Hz. When the ultrasonic sound wave reflects after touching the body surface and tissues, it provides images.
The History of Fetal Ultrasound
The creation of the black and white image of a developing fetus arrived in the mid-1950s. During that time, experts used high-frequency sound waves to generate those images. The invention of ultrasound Well, in the year of 1956, ultrasound was first used for medical purposes. Glasgow was the place where it saw its first light. Besides, ultrasound was the brainchild of engineer Tom Brown and Obstetrician Ian Donald.They were the first people who crafted the prototype system. They created it centered on an instrument that served the purpose of detecting the flaws in the industrial ships. However, in the 1970s, it became widely used.
Does ultrasound have any risks?
Ultrasound is safe for you and your baby when. Because ultrasound uses sound waves instead of radiation, it's safer than X-rays. Providers have used ultrasound for more than 30 years, and they have not found any dangerous risks.
Does 3d or 4d have any safety risks?
3D and 4D ultrasounds are just as safe as 2D scans since there is no form of radiation. While not considered a true risk, the rise in temperature caused by the sound waves that are used to create an image of the baby concern some parents.
