Physics of ultrasound
Acoustics, the science of sound, starts as far back as Pythagoras in the 6th century BC, who wrote on the mathematical properties of stringed instruments. Echolocation in bats was discovered by Lazzaro Spallanzani in 1794, when he demonstrated that bats hunted and navigated by inaudible sound, not vision. Francis Galton in 1893 invented the Galton whistle, an adjustable whistle that pr… Webb8 apr. 2024 · AIMMS LIBRARY ULTRASOUND VIDEO NO 25 Clinical-Ultrasound-I--Physics-and-Knobology.
