. Ivanov graduated from Leningrad Airforce Academy in 1959. While at the academy, he came up with the idea of using the recently discovered phenomenon of

nuclear magnetic resonance Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field (in the near field) and respond by producing an electromagnetic signal with a ...

for imaging purposes. In 1959, he filed his first application for Invention Certificate (a patent -like document used in the Soviet Union) titled "Free-precession proton microscope". Soon afterwards he filed three more applications. The second of his application (filed in March 1960) comprised a detailed description of the MRI principles, as was confirmed more recently. Originally this application was rejected as "unrealizable". However, in 1984 an Invention Certificate № 1112266 " A method for determination of internal structure of material objects" was finally issued in 1984, only after this method was demonstrated in other countries. After leaving the military, Ivanov returned to

. Despite his failure to commercialize his MRI invention, Ivanov continued his career as a prolific inventor. His name is listed on over 100 patents. He was a developer of apparatuses for space, aviation, marine and underground applications. He was the lead designer of two Soviet National standards: of angular velocity and of acceleration.
