In practice, the fields are not exactly homogeneous and in turn a precise knowledge of the spatial field profile is necessary when using a model-based reconstruction approach. In this work, we propose an efficient method for the measurement and a compact representation of the drive fields using a small three-axis coil sensor and solid harmonics.en2365-903320221, Suppl 1Infinite Science Publishinghttps://creativecommons.org/licenses/by/4.0/InformatikMedizinJournal Article10.15480/882.444210.18416/IJMPI.2022.220301510.15480/882.4442Other
