Abstract: Magnetic field measurements play a central role in Magnetic Particle Imaging (MPI). However, their determination is often a time-consuming process that involves sequentially scanning a given volume at predefined locations with a single magnetic field sensor. Therefore, an extensive amount of measurements is required to accurately characterize magnetic field generators, particularly those utilizing non-linear field generation processes. In this work, we introduce a single-shot magnetic field measurement system capable of capturing magnetic fields within a sphere with a 9 cm diameter at a measurement rate of 10 Hz. In comparison, a similar measurement conducted with a single 3D Hall probe moved by a robot previously took 4 min per volume measurement. We present magnetic field measurements of static MPI fields and characterize the accuracy of the single-shot measurement system. In addition, we discuss limitations on the field shapes that can be accurately measured.
