AB  - 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.
