Lazzaro Spallanzani, an Italian biologist, physiologist, professor, and priest, was born on January 10, 1729. He conducted various experiments that significantly contributed to the understanding of human and animal biology.

In 1794, Italian physiologist and biologist Lazzaro Spallanzani published the first paper on ultrasound. He studied bats and found that they use sound for navigation, which is known as echolocation. This discovery laid the foundation for modern medical ultrasound.

Lazzaro Spallanzani, the Italian biologist credited for discovering ultrasonography, passed away on February 12, 1799. His experiments and insights in physiology and biology laid the foundation for the development of ultrasound technology.

Jean-Daniel Colladon demonstrated that sound travels faster in water than in air, laying the foundation for understanding sound wave propagation.

Christian Andreas Doppler's 1841 treatise on the Doppler Effect revolutionized the understanding of spectral shifts in light due to motion. His work laid the foundation for Doppler ultrasound, a key technique in medical diagnostics.

Christian Doppler first postulated the Doppler effect, explaining changes in light wave frequency and later applied it to sound waves.

Pierre and Jacques Curie discovered piezoelectricity, a technology crucial for ultrasound probes to emit and receive sound waves.

Ultrasound was discovered in 1880 as a form of sound waves that have frequencies higher than the audible range for humans. It later became a common medical imaging procedure used in private ultrasound clinics and hospitals worldwide.

Reginald Fessenden developed an ultrasound-based collision avoidance system after the Titanic sinking, using high-frequency sound waves to detect objects.

Physicist Paul Langevin was commissioned to invent a device to detect objects at the bottom of the sea after the sinking of the Titanic. He created the hydrophone, which is now considered the first transducer.

In 1928, Russian physicist SY Sokolov was the first to conceptualize the use of ultrasound for imaging techniques. He focused on using this method to detect imperfections in metallic structures rather than for medical diagnostics. Despite his original intention, the device he invented produced shadow images that could be interpreted.

Karl Theodore Dussik, along with his brother Friederich, pioneered medical ultrasonography in the late 1930s. They used a 1.5-MHz transmitter to scan the human brain and produced images called 'hyperphonograms,' marking a significant advancement in ultrasound imaging.

In 1941, Donald Sproule developed a system where ultrasound waves were generated and detected by the same transducer, improving reflective techniques.

Neurologist Karl Dussik utilized ultrasonic waves for the first time in 1942 to detect brain tumors by transmitting an ultrasound beam through the human skull.

In 1948, George D. Ludwig, M.D. developed A-mode ultrasound, which was used for detecting gallstones.

In 1949, George Döring Ludwig utilized ultrasound technology to successfully detect gallstones, marking a significant advancement in medical diagnostics.

John J. Wild pioneered B-mode ultrasound imaging, producing two-dimensional images of internal structures, leading to advancements in soft tissue imaging.

Physician Inge Edler and Engineer C. Hellmuth Hertz performed the first successful echocardiogram.

In 1955, ultrasound was introduced for medical diagnosis.

Ian Donald was the first to combine ultrasound with diagnostic medicine in 1956. He initially used the device to measure the diameter of a fetus's head, showcasing the early application of ultrasound in medical imaging.

Physician Inge Edler and Engineer C. Hellmuth Hertz performed the first successful echocardiogram using an echo test control device from a Siemens shipyard.

George Kossoff of Australia engineers the Octason static scanner, which allows detailed fetal anatomy imaging, marking an important milestone in ultrasound development.

In 1963, the commercial use of B mode ultrasound devices started, allowing examiners to visualize two-dimensional images.

Don Baker, Dennis Watkins, and John Reid designed pulsed Doppler ultrasound technology, enabling imaging of blood flow in different layers of the heart.

Ultrasound imaging uses high-frequency sound waves to create images of the inside of the body. It is a non-invasive and versatile imaging modality used for various medical purposes.

Sam Maslak develops a machine in 1983 that sets new standards in spatial and contrast resolution, contributing to the advancement of ultrasound technology.

The BMUS Historical Collection was founded in 1984 to gather and preserve artifacts and materials related to diagnostic and therapeutic ultrasound in the UK.

Kazunori Baba from the University of Tokyo created 3D ultrasound technology and successfully produced three-dimensional images of a fetus.

In 1989, Daniel Lichtenstein introduced lung and general sonography in intensive care units, revolutionizing critical care practices.

Jonathan M. Rubin and Ronald S. Adler introduced power Doppler imaging, enhancing the visualization of weak flow signals in ultrasound imaging.

Ultrasound has evolved as a crucial diagnostic tool over the past 40 years, with major developments in the 1930s, 1940s, and 1970s. The progress in ultrasound technology required a multidisciplinary approach involving physics, physiology, medicine, engineering, and government.

In 2004, it was noted that the first experiments indicating the existence of non-audible sound were conducted on bats by Lazzaro Spallanzani. These experiments laid the foundation for the development of ultrasound technology.

In August 2020, an industry leading Private Healthcare Provider was mentioned in relation to ultrasound scans. The NHS revealed in 2018 that almost 43 million imaging tests were ordered in the UK, including ultrasounds, CT scans, and MRIs.

A session or event focused on answering questions related to using ultrasound for cancer screening purposes.
