Where did Ian Donald invent ultrasounds?

Ian Donald did not invent ultrasounds, but he was a pioneer in the use of ultrasound in medicine, particularly in obstetrics and gynecology. He is credited with developing the first practical real-time ultrasound scanner, which he used to perform the first successful ultrasound-guided amniocentesis in 1958. This device allowed him to visualize the fetus and diagnose fetal anomalies, revolutionizing the field of prenatal diagnosis.
