Abstract

Magnetic Particle Imaging (MPI) is based on the detection of super paramagnetic material by sampling a volume with a field free point (FFP) [1]. In order to cover the field of view (FOV) with a Lissajous trajectory [2], current scanners use drive fields to realize the FFP movement. In this contribution, an alternative trajectory, called a radial Lissajous trajectory, is proposed. This trajectory features a circular shape that is based on the same frequency ratio as the Lissajous trajectory, and can therefore be implemented on current scanners. As an initial study, a comparison between the proposed radial Lissajous trajectory and the conventional Lissajous trajectory is given with a focus on FOV patches.
