Concurrently, extensive research into the biological effects of ultrasound waves established that the diagnostic level used in medicine is safe, a critical finding that allowed the technology to be adopted globally without hesitation regarding patient safety. The primary driver was not medicine, but naval warfare.
Understanding Ultrasound Invented Signal Processing Fundamentals
The Physics Behind the Pictures To understand when ultrasound was invented , one must first grasp the fundamental principle that makes it work: the piezoelectric effect. In 1953, two Swedish physicians, Inge Edler and Carl Hellmuth Hertz, became the first to use ultrasound for cardiac imaging.
Around the same time, the first commercial diagnostic ultrasound machine, the Diasonograph, was being developed and introduced in the late 1950s. The transducer, the handheld wand used in scans, contains piezoelectric crystals that convert electrical energy into high-frequency sound waves and then back into electrical signals when the waves echo back from internal structures.

The First Commercial Machines While the theoretical and experimental work was happening in Glasgow, a parallel development was occurring in the United States. Two distinct communities began exploring the diagnostic potential of sound waves almost simultaneously.
