The benefits of travel | Nature Physics

Access through your institution Buy or subscribe Traditionally in NMR imaging a standing radio-frequency wave is created within the sample under study, causing the atoms' nuclear

magnetization to 'wobble' (or nutate); the subsequent precession of the magnetization is then picked up by a probe and processed into images. Brunner _et al_., however, have found

advantages to using a travelling, rather than a standing, radio-frequency wave. The motivation comes from the electrodynamics of the situation: the magnetic field must exhibit curvature, and

for a standing wave that means spatial variation in the magnitude of the field; for a travelling wave, however, the curvature can instead be accommodated in phase variation, which means

that the magnitude of the field is more uniform, and therefore better for imaging. This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your
