Curriculum Vitae

Marija Boberg studied mathematics at the University of Paderborn between 2011 and 2017. She received her master's degree with her thesis on "Analyse von impliziten Lösern für Differential-Algebraische Gleichungssysteme unter Verwendung von Algorithmischem Differenzieren". Currently, she is a PhD student in the group of Tobias Knopp for Biomedical Imaging at the University Medical Center Hamburg-Eppendorf and the Hamburg University of Technology.

Abstract: Magnetic particle imaging is an imaging modality, which determines the spatial distribution of super-paramagnetic nanoparticles by solving a linear system of equations. Using multi-patch approaches the field-of-view in MPI can be enlarged. Due to field imperfections a dedicated system matrix for each patch is required to reduce artifacts in the reconstructed image. However, this results in long calibration times. In this talk, techniques are presented to reduce the calibration time while maintaining high quality.
