Influence of magnetic field optimization on image quality achieved for efficient radon-based reconstruction in field free line imaging in MPI

Abstract

The use of a field free line in magnetic particle imaging promises a considerable increase in sensitivity of this new imaging technique. Furthermore, efficient reconstruction algorithms emerge for line acquisition in MPI, since it is possible to transform the data into Radon space. This allows for the use of well-known and powerful reconstruction algorithms like for instance the filtered backprojection, which will substantially speed up reconstruction time. In this work, a simulation study is presented, which analyzes the influence of magnetic field optimization on the image quality achieved for efficient Radon-based reconstruction.
