| The first MRI image was published in
Nature by Paul C. Lauterbur (1929-2007), in 1973.
The first MRI scan of a human body part was made by Sir Peter Mansfield (b. 1933), of the finger of his research student Dr Andrew Maudsley. The images were presented at a special meeting of the Medical Research Council in 1976. [Manfield] The first MRI body scan performed on a human took place on 3 July 1977, undertaken by Raymond Damadian (b. 1936), Larry Minkoff, and Michael Goldsmith. [How MRI Works]

Supported by Joseph H. Holmes (1902-1982),
Douglass Howry (b. 1920) produced in 1951, with William Roderic
Bliss and Gerald J. Posakony, both engineers, the 'Immersion tank
ultrasound system', the first 2-dimensional B-mode (or PPI, plan
position indication mode) linear compound scanner. Two dimensional
cross-sectional images were published in 1952 and 1953, which
convincingly demonstrated that interpretable 2-D images of internal
organ structures and pathologies could be obtained with ultrasound.
[History of
Ultrasound in Obstetrics and Gynecology] 3D ultrasound was first developed by Olaf von Ramm and Stephen Smith at Duke University in 1987. [Patent] Often these images are captured rapidly and animated to produce a "4D ultrasound". |
