Abstract

Starting from the basic principles of a Magnetic Particle Spectrometer (MPS), this paper explains the benefits and limitations of conventional spectral representation of the magnetization behavior of magnetic particles. After motivating the advantages of direct m(H) representation for particle analysis, it is shown how this curve, or at least its derivative, which is related to the point spread function, can be derived from the measured data. To illustrate, MPS results for Resovist® are presented, that show experimental evidence of hysteresis in dynamically acquired m(H) curves.
