Abstract

In Magnetic Particle Imaging (MPI), relaxation behavior of magnetic nanoparticles (MNPs) has enabled the inference of information about different MNP types and their local environments, such as viscosity and temperature. Previously, we have proposed and demonstrated an arbitrary waveform (AW) MPI scanner that facilitates operation in a wide range of drive field (DF) frequencies by eliminating the need for impedance matching. In this work, we propose a technique for simultaneous relaxation mapping at multiple DF frequencies in a single pass using an AW MPI scanner.

Key Contributions
  • Single-pass acquisition protocol for relaxation mapping
  • Multi-frequency measurement capabilities
  • Arbitrary waveform MPI scanner implementation
  • Enhanced efficiency in magnetic nanoparticle characterization
  • Novel approach to relaxation parameter estimation

This research builds upon the arbitrary waveform MPI scanner development presented at IWMPI 2022:
