Medical imaging: MRI rides the wave
Paul Glover1 & Richard Bowtell1
Abstract
An innovative approach for exciting and detecting signals in magnetic resonance imaging not only improves image quality but also enables radical changes in scanner design by freeing up space around the patient.
Magnetic fields varying at radio frequency (RF) are fundamental to nuclear magnetic resonance (NMR) and the related technique of magnetic resonance imaging (MRI). In NMR, RF fields are used in conjunction with a strong, constant magnetic field to excite hydrogen nuclei in water into precession.
- Paul Glover and Richard Bowtell are in the Sir Peter Mansfield Magnetic Resonance Centre, School of Physics and Astronomy, University of Nottingham, Nottingham NG7 2RD, UK.
