Abstract
Conventional magnetic particle imaging (MPI) relies on high-gradient selection fields to create field-free point (FFP) or field-free line (FFL) for spatial encoding; however, these fields require high power and limit scalability. We present a field free region-less (FFR-less), fully stationary MPI configuration that achieves 3-D spatial encoding without mechanical motion. The system integrates a single excitation field with a multi-receiver coil array, providing coverage of a 100 × 100 × 50 mm³ (extendable) field of view. Simulation results confirm nanoparticle localization without selection fields or motion, demonstrating a compact, power-efficient, and scalable path toward human-scale MPI.
