Image reconstruction in MPI is an ill-posed problem that can be addressed by regularization methods that each lead to a bias. Reconstruction bias in MPI is most apparent in a mismatch between true and reconstructed tracer distribution. This is expressed globally in the spatial support of the distribution and locally in its intensity values. In this work, MPI reconstruction bias and its impact are investigated and a two-step debiasing method with significant bias reduction capabilities is introduced.en2365-903320202, Suppl 113Infinite Science Publishinghttps://creativecommons.org/licenses/by/4.0/InformatikMedizinJournal Article10.15480/882.442210.18416/IJMPI.2020.200904110.15480/882.4422Journal Article
