Abstract

Magnetic Particle Imaging evolves rapidly and human scanners are conceivable, already. However, the growing scanner size and therefore the increasing data within the field of view give rise to several unsolved problems. The reconstruction process, solving an inverse problem with the measured signal and the system function, is a storage consuming procedure for high resolution 3D imaging. Additionally, the size of the field of view strongly depends on the used gradient field and field amplitudes. Due to technical as well as medical limitations, such as specific absorption rates and peripheral nerve stimulation, the conventional procedures will not be sufficient to image large regions of interest. This paper compares and discusses approaches enlarging the field of view that might be used to reduce the reconstruction process and/or enlarge the field of view despite limited technical properties.
