abstract = {The highest magnetic field strength for human-sized
magnetic resonance imaging (MRI)currently lies at 11.7
tesla. Given the opportunities for enhanced sensitivity and
improved dataquality at higher static magnetic fields,
several initiatives around the world are pursuing
theimplementation of further human MRI systems at or above
11.7 tesla. In general, members ofthe magnetic resonance
(MR) research community are not experts on magnet
technology.However, the magnet is the technological heart of
any MR system, and the MRI community ischallenging the
magnet research and design community to fulfill the current
engineering gap inimplementing large-bore, highly
homogeneous and stabile magnets at field strengths that
gobeyond the performance capability of niobium–titanium.
In this article, we present an overviewof magnet design for
such systems from the perspective of MR scientists. The
underlyingmotivation and need for higher magnetic fields are
briefly introduced, and system designconsiderations for the
magnet as well as for the MRI subsystems such as the
gradients, theshimming arrangement, and the radiofrequency
hardware are presented. Finally, importantlimitations to
higher magnetic fields from physiological considerations are
described, operatingunder the assumption that any
engineering or economic barriers to realizing such systems
willbe overcome.},
