English physician Ian Donald in 1957
It is used for assessing and diagnosing many medical problems, all over the body - but particularly useful for abdominal, renal and urinary tract problems. My friends child had a US scan on her knee to find out what a mysterious lump was (a bursar)

The A-mode scan had been used for early pregnancy assessment (detection of fetal heart beat), cephalometry and placental localization in Europe, Britain, United States, Japan, China, USSR, Poland and Australia in the early 1960s, the measurement of the biparietal diameter (BPD) having been invented by Ian Donald in 1961 and further expanded in his department by James Willocks, basing on improvements in the 'bright-up' markers and the electronic caliper system. The measurements were done 'blindly' without actually seeing the structures under study. Visualising the gestational sac by B-mode ultrasound was first described by the Donald and MacVicar team in 1963. In 1965, they were able to demonstrate a 5-weeks gestational sac. The Gestational sac diameters in the assessment of fetal maturity was described by Lou M Hellman and M Kobayashi in 1969 and by Pentti Joupilla (Finland), Salvator Levi (Brussels) and E Reinold (Vienna) in 1971 in relation to early pregnancy complications. Kobayashi also described the ultrasonic appearance of extra-uterine pregnancy using bi-stable B-mode ultrasound in 1969. Kenneth Gottesfeld in Denver reported in 1970 a large series of patients where fetal death in utero was diagnosed solely on bistable ultrasound scan. Read on the link below for other details.

Woody Norris
Inspired by Doppler radar, Norris in 1967 created a sonar tool to isolate different movements inside the human body. This Transcutaneous Doppler system, which sends ultrasound through the skin, was designed to listen to targeted sounds, and was a precursor to the sonogram.
