Abstract

Due to the superposition of the high magnitude drive field signal and the low magnitude particle signal in magnetic particle imaging (MPI), the received signal has to be separated at its fundamental frequency [1]. This is often done by filtering causing DC offset drifts in the particle answer using x-space reconstruction. These errors are currently corrected by dividing the FOV in partial FOVs [2]. However, small FOV sizes reduce the temporal resolution if the region of interest stays the same. This work proposes a combination of filtering and cancellation to prevent the fundamental frequency of the particle signal as well as provide the possibility of larger FOVs and presents three different cancellation coil techniques.
