Early use of ultrasound for a medical purpose
One of the first uses of ultrasonic energy applied for medical diagnostic purposes was by Dr. George D. Ludwig at the Naval Medical Research Institute, Bethesda, Maryland in 1947-1949, and subsequently at the Massachusetts Institute of Technology. He demonstrated thatgallbladder stones could be detected by an ultrasonic echo method using A mode metal flaw detectors and naval sonar. The documentation of Dr. Ludwig's research came by way of his daughter, Rosemary Ludwig Turner.
