The first time ultrasound was used for clinical reasons was in 1956. It was used in Glasgow by an Obstetrician named Ian Donald and an engineer named Tom Brown. These two men developed the first prototype system for ultrasound, but it wasn’t perfected until the end of the 1950s.
Pioneered use in monitoring fetal development.
Ian Donald was the pioneer of obstetric ultrasound. Using A-mode equipment he studied the lumps, cysts, and fibroids to differentiate them from the solid masses in the body.
