A method for accelerating projection-based magnetic particle imaging

Year: 2023

Type: preprint

Abstract: Magnetic particle imaging (MPI) is an imaging method that can visualize magnetic nanoparticles in positive contrast, without radiation exposure. Recently, we proposed an image reconstruction method for projection-based MPI (pMPI), in which the system function was incorporated into the simultaneous algebraic reconstruction technique and the total variation minimization was used to suppress noise and artifacts. This study investigated the usefulness of our method for accelerating pMPI through simulation and phantom experiments with varying number of projections. The present results suggest that our method is useful for accelerating pMPI without deteriorating the image quality.
