Magnetic Particle Imaging

MATTHIAS GRÄSER was born in Neuwied, Germany in 1982. He received his Dipl.-Ing. in Mechatronics from the Karlsruhe Institute of Technology, Germany in 2010. During an internship at Otto Bock Healthcare Systems, Vienna, Matthias Gräser built a testing module for the main electronic unit of the C-Leg prosthesis system. He wrote his student research thesis at the Institute for Information Processing Technologies. The aim was to examine the applicability of different dry electrodes for long time ECG monitoring. He finished his university studies with his diploma thesis "Thresholds of inductive muscle stimulation from 7.4 to 25 kHz". In 01/2011 he joined the Magnetic Particle Imaging (MPI) group as a research assistant at the Institute of Medical Engineering, Lübeck.
