The use of conventional nuclear magnetic resonance is limited by

the fact that the object needs to be carried to the NMR equipment

and needs to fit inside large superconducting magnets. Both

limitations are removed by single-sided NMR probes based on open

magnets specially adapted to the object under study. These can be

inexpensive and portable sensors that give access to a large

number of applications inaccessible with using conventional magnet

geometries. Substantial improvements in the magnet design,

detection electronics, and the implementation of suitable

techniques to work in the inhomogeneous magnetic fields of open

magnets have allowed scientists and engineers to measure

relaxation-time distributions, diffusion coefficients, 3D images,

velocity distributions, and even highly resolved NMR spectra in

the stray field of the magnet. This book is the first

comprehensive account describing the key issues to be considered

at the time of designing and building open magnets, and

summarizing the arsenal of pulse sequences available today for

material analysis.

This book describes the design of the first functioning single-sided tomograph, the related measurement methods, and a number of applications in medicine, materials science, and chemical engineering. It will be the first comprehensive account of this new device and its applications. Among the key advances of this method is that images can be obtained in much shorter times than originally anticipated, and that even vector maps of flow fields can be measured although the magnetic fields are highly inhomogeneous. Furthermore, the equipment is small, mobile and affordable to small and medium enterprises and can be located in doctors' offices.
