when were ultrasounds invented

Ultrasound as a technology grew out of 19th‑century physics, but medical ultrasound was developed in the mid‑20th century, with practical diagnostic scanners appearing in the 1950s and becoming widely used in the 1960s.

Quick Scoop

  • The physical basis of ultrasound (piezoelectric effect) was discovered in 1880 by Pierre and Jacques Curie, allowing deliberate generation of high‑frequency sound waves.
  • Industrial echo devices for detecting flaws in metal, such as the Supersonic Reflectoscope, were built around 1940 and showed how echoes could reveal internal structures.
  • Early medical experiments with ultrasound began in the 1940s , including attempts to detect brain tumors and treat conditions like sciatica.
  • English‑born physicist John Wild used ultrasound on human tissue by 1949 and is often called the “father of medical ultrasound.”
  • In the 1950s , Ian Donald and colleagues in Glasgow adapted industrial ultrasound for medicine; by 1958 they published a landmark paper on using ultrasound to investigate abdominal masses and early obstetric applications.
  • The first commercially practical medical scanners appeared in the early 1960s , making diagnostic ultrasound a routine imaging tool.

Short timeline

  1. 1880 – Curie brothers discover piezoelectricity, enabling ultrasonic wave generation.
  1. 1910s–1940 – Sonar and industrial echo devices developed for military and engineering use.
  1. 1940s – First medical experiments (brain tumors, pain conditions) using ultrasound energy.
  1. Late 1940s–1950s – John Wild, Ian Donald and others pioneer diagnostic imaging with ultrasound.
  1. Early 1960s – First widely usable diagnostic ultrasound scanners reach clinics, and obstetric ultrasound starts to spread globally.

In everyday terms, people often say ultrasounds were “invented” in the 1950s–60s , when machines that could safely image the body (especially in pregnancy) became practical and began to be used at scale.
