MPI with a mechanically rotated FFL

An alternative encoding scheme using a field free line (FFL) promises a ten-fold higher sensitivity and faster reconstruction algorithms for magnetic particle imaging (MPI) [1]. Yet, different scanner designs for two-dimensional imaging have been introduced [2,3]. This paper introduces a simulation study that combines both approaches which relies on permanent magnets and includes a rotational device as proposed in [4]. Therefore, this work uses a rotationally symmetric design as a basis and suggests a potential assembly. This assembly is realized and used initially to capture one-dimensional images which are shown below.
