History of Medical Ultrasound

Milestones, Pioneers and Key Developments in Diagnostic Ultrasound

Chapter 1.2 History of Medical Ultrasound Updated 2026 Educational Reference

Overview → Medical ultrasound grew from physics discoveries in the 19th and early 20th centuries into a safe, non‑ionizing imaging modality used worldwide. Key breakthroughs include the discovery of the piezoelectric effect, development of sonar and ultrasonic instrumentation, the first diagnostic transmission experiments in the 1940s, the start of echocardiography in the 1950s, and the later arrival of real‑time gray‑scale and Doppler techniques that made ultrasound ubiquitous in clinical practice.

Year	Milestone	Notes
1880	Curie Brothers	Discovery of the piezoelectric effect — foundation for ultrasound transducers.
1917	Paul Langevin	Ultrasonic sonar research and generation/detection methods used in early ultrasonic devices.
1942	Karl Dussik	Early diagnostic transmission ultrasound studies (brain imaging experiments).
1953	Edler & Hertz	First practical echocardiography — use of ultrasound to study the heart.
1956	Shigeo Satomura	Applied Doppler techniques to measure blood flow (medical Doppler ultrasound beginnings).
1958	Ian Donald & Tom Brown	Pioneered obstetric ultrasound and practical clinical scanners.
1960s	1960s	Improvements in real‑time and gray‑scale imaging made ultrasound much more useful clinically.
1970s	1970s	Portable scanners and Doppler enhancements broadened point‑of‑care use.
1980s	1980s	Color Doppler and widespread clinical adoption across specialties.
