History Flashcards
[person, year] first to study echolocation among bats, which forms the basis for ultrasound physics
1794
Physiologist Lazzaro Spalanzanni
[person, year] discover piezoelectric electricity. Ultrasound transducers (probe) emit and receive sound waves by way of piezoelectric effect
1877
Pierre and Jacques Curie
Piezin - meaning
To press
[event] principle of pulse echo technique for detection of underwater bodies were under investigation
Prior to WWI
[event] developed SONAR [Sound Navigation and Ranging] to know presence of enemies
WWI
[person, year] commissioned to invent a device that detected objects objects under the sea (icebergs);
Invented first transducer “hydrophone”
1915
Paul Langevin
[person, year] (first important publication of ultrasound) inspired modern diagnostic techniques
1916
Chilowsky and Langavin
[person, year] earliest researchers and published result on the bioeffect of pulse echo/utz as a form of energy
1927-1929
Warod, Loomis, Johnson
[person, year] focused utz in water bath and induced massive cerebral lesions in experimental animals by insinuating them with focused 1 MHz. Attempts were made to develop utz as an alternative to radiation therapy
1927-1929
Lym and Putnam
[person, year]
used to treat European Soccer teams as a form of physical therapy, to appease arthritic pain and eczema and to sterilize vaccine
1920s-1940s
Joan Baker
[person, year] took out patients on utz device used for detecting metal flaws
1930s-1940s
Sandoval and Firestone
[person, year] First to use sonography for medical diagnosis. He transmitted an utz beam through the human skull in attempts of detecting brain tumors
1942
Neurologist, Karl Dussik
[person, year] developed A-mode ultrasound equipment to detect gallstones
1948
George D. Ludwig,
[person, year] produced first cross-sectional utz image
1950
Howry and Bliss
Proliferation of wider clinical application of diagnostic utz
[person, year] developed an ophthalmic scanner
Mid 1950s
Baun
[person, year] leading pioneers of B-mode utz equipment including 2D B-mode linear compound scanner
[person, year] invented handheld B-mode device for breast tumors
1949-1951
Douglas Howry and Joseph Holmes
John Reid and John Wild
[person, year] first successful echocardiogram
1953
Physician Inge Edler and Enginner C. Helmouth Hertz
[person, year] Assembled first compound scanner consisting of water-filled tank in which patient was immersed surrounded by track in which transducer was moved in a series of compound motions and published cross-sectional image of improved quality
1957
Howry and Holmes
[person, year] incorporated utz into the ob/gyn field of medicine
1958
Dr. Ian Donald
