In this study, we present a narrow-band Magnetic Particle Imaging (MPI) system based on the measurement of the 3f0 harmonic of magnetic nanoparticles. A spot sample is used to measure the point spread function (PSF). The spatial resolution of the system estimated from the full width at half maximum of the PSF is 2 mm and 2.5 mm in z- and x-direction, respectively. Phantom experiments are performed to demonstrate the feasibility of the proposed method for MPI using a single harmonic. In addition, the experimental results indicate that two lines of the MNP sample with a distance of 3 mm can be distinguished in x- and z-directions. It indicates that the measured spatial resolution is better than 2.5 mm, which fits very well with the estimated spatial resolution from the PSF.
