Magnetic particle imaging (MPI) is an imaging modality that measures the response of magnetic nanoparticle tracers
to alternating magnetic fields. There has recently been exploration into multi-contrast MPI, in which the signal
from different tracer materials or environments is separately reconstructed, resulting in multi-channel images that
enable temperature or viscosity quantification. In this work, we investigate the channel leakage in multi-contrast
MPI reconstruction and we introduce a two-step measurement and reconstruction method to quantify and reduce
channel leakage between multi-contrast MPI channels.
