Eddy current-shielded x-space relaxometer for sensitive magnetic nanoparticle characterization

Rev Sci Instrum. 2016 May;87(5):055109. doi: 10.1063/1.4950779.

Abstract

The development of magnetic particle imaging (MPI) has created a need for optimized magnetic nanoparticles. Magnetic particle relaxometry is an excellent tool for characterizing potential tracers for MPI. In this paper, we describe the design and construction of a high-throughput tabletop relaxometer that is able to make sensitive measurements of MPI tracers without the need for a dedicated shield room.
