Dynamic concentration reconstruction for magnetic particle imaging using splines

Main Article Content

Christiane Schmidt (Universität Hamburg), Christina Brandt 


4D Magnetic Particle Imaging (MPI) reconstructions with high temporal resolution are of high relevance for diagnostic purposes. In multi-patch measurements the data for single patches is not continuous. During the scan of one patch no data is acquired for the remaining patches. This impedes regularization by similarity of subsequent frames. We propose a method that models the dynamic tracer concentration with cubic B-splines which allows for reconstructions with high temporal resolution  from only few frames.
