Towards multidimensional x-space magnetic particle imaging for improved resolution

In this work,a method to achieve higher, more isotropic resolution for x-space MPI through analyzing various FFP trajectories and developing multidimensional transmit/receive hardware was presented. However, many parameters remain to be optimized for this technique, including the various tradeoffs between pFOV coverage, scanning speed, and resolution. Additional hardware challenges include precise control of the FFP through controlling the phase of the transmit fields and compensating for received particle signal based the anisotropic sensitivity profiles of the transmit and receive coils.
