Imaging reconstruction
WitrynaMagnetic Particle Imaging (MPI) is an imaging modality that exploits the nonlinear response of superparamagnetic iron oxide nanoparticles (SPIONs) to a time-varying magnetic field. In the past years, various scanner topologies have been proposed. Witryna12 kwi 2024 · However, during image reconstruction artifacts can be introduced and when coupled with time-consuming postprocessing procedures, limits this technique from becoming a routine imaging tool for biologists. To address these issues, an accelerated, artifact-reduced reconstruction algorithm termed Joint-Space-Frequency …
