Adaptive Permissible Region Strategy for Magnetic Particle Imaging

Magnetic particle imaging (MPI) is a new kind of molecular imaging technique which is designed to locate the superparamagnetic iron oxide (SPIO) with high resolution and sensitivity. The inverse problem of MPI is a challenge problem and many reconstruction methods have been proposed. In this paper, we proposed the adaptive permissible region (APR) strategy to promote the reconstruction efficiency. We apply APR strategy on Kaczmarz method and verify its performance with OpenMPI data set. As a general strategy, APR strategy can obviously reduce the reconstruction time in all conditions, and even promote the reconstruction result with proper parameter
