Abstract: Magnetic Particle Imaging (MPI) is a highly sensitive imaging modality, which allows the visualization of magnetic tracer materials with a temporal resolution of more than 40 volumes per second. In MPI the size of the field of view scales with the strength of the applied magnetic fields. In clinical applications this strength is limited by peripheral nerve stimulation and specific absorption rates. Therefore, the size of the field of view is usually no larger than a few cubic centimeters. To bypass this limitation additional focus fields and/or a external object movements can be applied. In this work we investigate the later approach, where an object is moved through the scanner bore one step at a time, while the MPI scanner continuously acquires data from its static field of view. Using 3D phantom and 3D+t in-vivo data it is shown that the data can be jointly reconstructed after reordering the data with respect to the stepwise object shifts and heart beat phases.
