Using an industrial ultrasonic flaw detector, they obtained time-varying echoes transcutaneously from within the heart. The first clinical applications of M-mode(More)
In the early 1950's, research was started at the University of Lund on the use of ultrasound as a diagnostic tool in cardiology, neurology, and gynecology.
