This volume provides a comprehensive overview of recent developments in magnetic particle imaging (MPI), a novel imaging modality. Using various static and oscillating magnetic fields, and tracer materials made from iron oxide nanoparticles, MPI can perform background-free measurements of the particles' local concentration. The method exploits the nonlinear remagnetization behavior of the particles and has the potential to surpass current methods for the detection of iron oxide in terms of sensitivity and spatiotemporal resolution. Starting from an introduction to the technology, the topics addressed include setting up an imaging device, assessment of image quality, development of new MPI tracer materials, and the first preclinical results. This is the first book to be published on magnetic particle imaging, and it will be an invaluable source of information for everyone with an interest in this exciting new modality.

Tobias Knopp erlautert die Rekonstruktion von MPI-Daten und entwickelt auf Grundlage eines Modells der MPI-Signalkette eine effiziente Methode zur Bestimmung der Systemmatrix. Fur die Rekonstruktion der ortlichen Partikelverteilung nutzt er einen gewichteten, regularisierten Kleinste-Quadrate-Ansatz. Im zweiten Teil der Arbeit stellt der Autor verschiedene neuartige Spulentopologien vor."

In these proceedings, an overview on recent results of a novel imaging modality based on magnetic nanoparticles is given. This imaging concept, called magnetic particle imaging (MPI), falls into the category of functional imaging and, hence, the magnetic nanoparticles may serve as tracers of metabolic processes. Today, there are interesting challenges within the practical set-up of a scanning device and also in the design of new MPI nanoparticles. During this workshop at the University of Lubeck in 2010, scientists from chemical engineering, biology, electrical engineering, physics, computer sciences and medicine discussed the promises and challenges of MPI.
