In single harmonic magnetic particle imaging (MPI), a reconstructed image can be obtained by deconvolution using the point spread function (PSF) of the 3rd harmonic. However, harmonic signals from superparamagnetic iron oxide nanoparticles (SPIOs) at the edge of the field of view (FOV) cannot be picked up, leading to artifacts in the reconstructed image. We propose an improved single harmonic MPI method using perpendicular magnetization to compensate for harmonic data loss. Experimental results show that the image reconstruction quality is improved using our method.
