Advances in instrumentation and tracer materials are still required to enable sensitive and accurate 3D temperature monitoring by magnetic particle imaging. We
Background: Patterning defect metrology requires data interpretation with classification, each well-suited to machine learning (ML). Defect classification
In this work we investigate how the MPI resolution changes as a function of signal harmonics. Based on a simulation study that models a lock-in measurement of
