Temporal Polyrigid Registration for Patch-based MPI Reconstruction of Moving Objects

Abstract

In Magnetic Particle Imaging, the size of the field of view can be increased with static focus fields resulting in imaging patches. Patches are acquired successively and combined during or after image reconstruction. However, the occurrence of motion may result in artifacts in the reconstructed images. In this contribution, a temporal polyrigid registration is proposed to combine reconstructed MPI patches by predicting a possible object motion. The experiments use different two-dimensional simulated MPI acquisition scenarios. It is shown that our approach reduces motion artifacts in dependence of the used patch overlaps successfully.
