Abstract
Pulsed magnetic particle imaging (MPI) allows the use of long relaxation time magnetic particles to achieve high-resolution images. In this study, we proposed a super-resolution imaging method for pulsed MPI, which can further enhance its spatial resolution. We validated our approach using autonomously synthesized long relaxation time shape anisotropic nanoparticles on our in-house-built 1D MPI system. The results demonstrate a spatial resolution of 1.0 mm under a gradient field of 1.2 T/m.
