MPI field generator design for an FFL based image acquisition

In conventional MPI scanners the magnetic nano particle concentration distribution is acquired by moving a field free point (FFP) through the FOV [1]. This method allows the sampling of a signal from a small point-like area per time. To gain a higher SNR, it was suggested to increase the simultaneously acquired volume by introducing the principal of a field free line (FFL) to MPI [2]. We propose a new field generator geometry which is capable of creating an FFL with a simpler coil geometry than the existing approaches.
