Summary:Magnetic particle imaging is a novel method of imaging the spatial distribution of magnetic nanoparticles. When considering the practical application of magnetic particle imaging, it is important to correct the inhomogeneous sensitivity of the receiving coil together with the feedthrough interference. In this study, we developed a simple and practical method for these corrections in which projection data are multiplied by correction factors obtained by fitting projection data acquired in a blank scan to a sixth-degree polynomial. Phantom experiments suggest that our method can be simply and easily implemented to realize the above corrections.
