Size-Optimized Magnetite Nanoparticles for Magnetic Particle Imaging
Abstract
We present experimental results to demonstrate that there is an optimum size for magnetite nanoparticles that are used to generate MPI signal, where the signal is detected as the third harmonic of nanoparticle magnetization, M, for any driving field frequency, v . Our experimental results, for an arbitrarily chosen v = 250 kHz, agree with predictions for a nanoparticle magnetization model based on the Langevin theory of superparamagnetism.
