Multiresolution Magnetic Particle Imaging of Vessel Structures with Support Detection

In Magnetic Particle Imaging, the distribution of a tracer is measured. In most practical cases, the tracer is only present at few areas and most of the image consists of background. Therefore, it seems promising to detect the support of the tracer and include this knowledge in the reconstruction process. In this work, a method is proposed which performs support detection in a multiresolution analysis and includes certainty about the estimation via a weighting in the optimization process. The results show that this procedure improves the structural similarity index.
