Abstract

A magnetic resonance imaging system can include a magnetic field generator, an image acquisition region and a radiofrequency system including at least one radiofrequency antenna. The radiofrequency system can emit a radiofrequency excitation pulse into the image acquisition region and receive magnetic resonance signals from the image acquisition region. The magnetic field generator can include at least one magnet to generate a magnetic field in the image acquisition region, a magnet holder to carry the at least one magnet and a rotation system to position the magnet holder along a rotation trajectory.
