  Magnetic Particle Imaging (MPI) is a highly sensitive imaging method that
enables the visualization of magnetic tracer materials with a temporal
resolution of more than 46 volumes per second. In MPI the size of the field of
view scales with the strengths of the applied magnetic fields. In clinical
applications those strengths are limited by peripheral nerve stimulation,
specific absorption rates, and the requirement to acquire images of high
spatial resolution. Therefore, the size of the field of view is usually a few
cubic centimeters. To bypass this limitation, additional focus fields and/or
external object movements can be applied. In this work, the latter approach is
investigated. 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 a 3D phantom and dynamic 3D in vivo data it is shown that the data from
such a moving table experiment can be jointly reconstructed after reordering
the data with respect to the stepwise object shifts and heart beat phases.
