Curriculum Vitae

Tobias Knopp received his Diplom degree in computer science in 2007 and his PhD in 2010, both from the University of Lübeck with highest distinction. For his PHD on the tomographic imaging method Magnetic Particle Imaging (MPI) he was awarded with the Klee award from the DGBMT (VDE) in 2011. From 2010 until 2011 he led the MAPIT project at the University of Lübeck and published the first scientific book on MPI. In 2011 he joined Bruker Biospin to work on the first commercially available MPI system. From 2012 until 2014 he worked at Thorlabs in the field of Optical Coherence Tomography (OCT) as a software developer. In 2014 he has been appointed as Professor for experimental Biomedical Imaging at the University Medical Center Hamburg-Eppendorf and the Hamburg University of Technology.

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.
