Comparison of human-scale MPI system concepts using a 3D arbitrary-waveform magnetic particle spectrometer

In the field of Magnetic Particle Imaging (MPI) hybrid methods are utilizing the simplicity and high SNR of magnetic particle spectrometers to complement imaging by characterizing particles and measuring system matrices for fast system calibration. In this contribution we utilize the flexibility of our 3D arbitrary-waveform magnetic particle spectrometer to measure the system matrices of three MPI scanner concepts inspired by clinical-scale head-sized MPI systems. Using these system matrices we are able the compare reconstructed images under the same noise, particle and reconstruction conditions gathering first insights into the imaging properties of different scanners.
