High resolution magnetic particle imaging with low density trajectory

H. Medimagh, T.M. Buzug, Osama A. Omer

Abstract

The spatial resolution is an important factor in MPI. The trajectory density is one of many parameters affecting the spatial resolution of MPI. To obtain a high-resolution (HR) concentration one can increase the trajectory density or increase particle diameters. However, increasing the trajectory density leads to increase of the computational complexity. Also, large particles suffer from relaxation effects. In addition, imaging with system matrix that exhibits high grid leads to higher resolution but requires much calibration time for the system matrix. This work suggests to use small particle diameters with low density trajectory while sampling with low dimension system matrix and fuses these low-resolution (LR) concentrations as a post process to get HR concentrations.
