Tutorials of IWMPI 2019


Lecture 1: Introduction into MPI Instrumentation and Image Reconstruction

Jochen Franke, Product Manager Magnetic Particle Imaging, System Engineering & Integration, Bruker BioSpin MRI, Germany

The scope of the first part of this tutorial is to present an overview of signal generation and spatial encoding schemes used nowadays in Magnetic Particle Imaging. State-of-the-art MPI scanner topologies will be identified ranging from classical Field-Free-Point and Field-Free-Line systems to single-sided, traveling-wave and hybrid imaging systems. A brief description of magnetic field components with their field requirements and their functionality will be highlighted. With the help of block diagrams, MPI system components of classical signal chains will be described and characterized.

The second part of this tutorial covers the basic introduction of state-of-the-art reconstruction techniques used in Magnetic Particle Imaging. At most, the differences and similarities between the frequency- and time-space reconstruction approach will be addressed. With this overview, advanced techniques such as enlarged field of view or multi-color reconstruction will be discussed. Model-based reconstruction approaches and the usage of complementary information from other modalities will lead to the outlook and discussion section.

For all topics addressed during this tutorial, scientific papers will be highlighted to provide in-depth training material.



Jochen Franke studied Engineering Physics and Biomedical Engineering at the University of Applied Sciences Münster (Germany) and the Technical University RWTH Aachen (Germany). His PhD on “MPI-MRI hybrid imaging systems” he performs at Bruker BioSpin MRI, Ettlingen (Germany) and the Technical University RWTH Aachen (Germany). In 2016 Jochen became the Group Leader MPI Systems and Integration and in 2018 the Product Manager MPI Systems at Bruker BioSpin MRI, Ettlingen (Germany).

Lecture 2: Introduction into Magnetomotion

Klaas Bente, German Federal Institute for Materials Research and Testing (BAM), Germany

Many motile microorganisms swim and navigate in chemically and mechanically complex environments, such as the human vascular system. These organisms can be functionalized and directly used for applications (biohybrid approach), but also inspire designs for fully synthetic microbots. The most promising designs of biohybrids and bioinspired microswimmers include one or several magnetic components, which lead to sustainable propulsion mechanisms and external controllability.

This tutorial addresses such magnetic microswimmers, which are often studied in view of certain applications, mostly in the biomedical field. First, propulsion systems at the microscale are reviewed and the magnetism of microswimmers is introduced. The presentation of state-of-the-art magnetic biohybrids and bioinspired microswimmers is structured gradually from mostly biological systems toward purely synthetic approaches. Finally, currently less explored aspects of this field ranging from in vivo imaging to swarm control are discussed.



Klaas Bente studied Medical Engineering Science and did his PhD on real-time field-free line MPI at the Institute of Medical Engineering at the University of Lübeck, Germany, in 2016. Thereafter, he worked as a postdoc at the Max Planck Institute of Colloids and Interfaces in Potsdam, Germany, focusing on magnetic microswimmer imaging. He now works as a scientist on ultrasound imaging at the German Federal Institute for Materials Research and Testing (Bundesanstalt für Materialforschung und -prüfung, BAM), Berlin, Germany.
