Peter Mansfield - Scientific Career

Scientific Career

Mansfield graduated with a BSc from Queen Mary's in 1959. His final-year project, supervised by Dr. Jack Powles, was to construct a portable, transistor-based spectrometer to measure the Earth's magnetic field. Towards the end of this project Powles offered Mansfield a position in his NMR research group. Powles' interest was in studying molecular motion, mainly liquids. Mansfield's project was to build a pulsed NMR spectrometer to study solid polymer systems. He received his PhD in 1962; his thesis was titled Proton magnetic resonance relaxation in solids by transient methods. In the same year he was invited to go and work for a post-doctoral period for Charlie Slichter at the University of Illinois at Urbana, Illinois, where he carried out an NMR study of doped metals.

In 1964 he returned to England to take up a place as a Lecturer at Nottingham University where he could continue his studies in multiple-pulse NMR. He was successively appointed Senior Lecturer in 1968 and Reader in 1970. During this period his team developed the MRI equipment with the help of grants from the Medical Research Council. It was not until the 1970s with Lauterbur's and Mansfield's developments that NMR could be used to produce images of the body. In 1990 Mansfield was appointed Professor of the Department of Physics until his retirement in 1994.

Mansfield is credited with showing how the radio signals from MRI can be mathematically analysed, making interpretation of the signals into a useful image a possibility. He is also credited with discovering how fast imaging could be possible by developing the MRI protocol called echo-planar imaging. Echo-planar imaging allows T2* weighted images to be collected many times faster than previously possible. It also has made functional magnetic resonance imaging (fMRI) feasible.
