MRI System,Since introduction in the early 1970s by Lauterbur, Damadian, and Mansfield, MRI has experienced a tremendous progress. A lot of “brainpower” was invested to optimize this fascinating and important imaging technique.

Low-Field-Specific Physical Aspects,In low-field MR scanners, some imaging parameters are different from high-field systems. These different characteristics can be of advantage or disadvantage, depending on the imaging situation (Kuhl et al. 2008; Hoult et al. 1986).

Low-Field Imaging Technique,We have taken a look at the construction of MRI systems, how they work, and which low-field-specific aspects of physics have to be considered. Now, before we consider clinical imaging, we will think about ways to optimize low-field scanning, which advantages can we use and which drawbacks have we to be aware of.

Clinical Application,The hypothesis of this book is, to put in a nutshell, that low-field MRI systems, with a field strength of less than 0.4 T and with a permanent magnet, are full-scale whole-body imaging machines.

Site Planning,vantages of these systems influence the concept of the scan site and enable to realize MR imaging units in locations that are impossible to service with high-field systems. However, there are certain prerequisites that must be taken into account.
