Vladislav Alexandrovich Ivanov (Russian: Владислав Александрович Иванов; 1936-2007) was a Soviet physicist and engineer, who proposed in 1959 the basic principles of magnetic resonance imaging, decades before this technique was demonstrated by Paul Lauterbur.
While at the academy, he came up with the idea of using the recently discovered phenomenon of nuclear magnetic resonance for imaging purposes.
In 1959, he filed his first application for Invention Certificate (a patent equivalent in the Soviet Union) titled "Free-precession proton microscope".
The second of his application (filed in March 1960) comprised a detailed description of the MRI principles, as was confirmed more recently.
After leaving the military, Ivanov returned to Leningrad, where he enrolled in Saint Petersburg Electrotechnical University, which he graduated from in 1966 with a PhD in Engineering.
