Software Implementation of Greedy Optimized MPS Sequences

Multi-dimensional magnetic particle spectrometers provide fast and high quality hybrid system matrix measurements, using different DC offsets to emulate the same saturation that magnetic nanoparticles are exposed to in a real scanner. The electrical implementation of these offsets poses signal generation challenges that impact runtime and power dissipation. In this work, we address the challenges of minimizing sign changes of DC sources with H-bridges and efficient offset sorting for arbitrary numbers of offset channels.
