Asymmetric Scanner Design for Interventional Scenarios in Magnetic Particle Imaging

Abstract

Magnetic particle imaging is an imaging modality that acquires quantitative information about the spatial distribution of magnetic nanoparticles. In combination with an excellent spatial and temporal resolution and due to the fact that no harmful radiation is used, the imaging technique offers possibilities with respect to medical application. As such, interventional scenarios, where it is mandatory to visualize the used instruments, are a perfectly suitable area of application. This paper describes the results of a feasibility study where a novel single-sided coil arrangement based on approximated elliptical coils is designed to be integrated into a patient table. Using such coils perfectly matches the requirements of good patient access, large field of view (FOV), and available space in the table. A small change in the aspect ratio leads to an enlarged FOV with sufficient gradient strength in all directions.
