Abstract

In a conventional magnetic particle imaging (MPI) method, a reconstructed image is mainly calculated from odd harmonics of the magnetization response. However, the image blurring and artifacts appear due to the interference of the magnetization response generated from magnetic nanoparticles (MNPs) around the field free point (FFP), so that the image resolution is degraded. Therefore, we proposed a new image reconstruction method that was focused on the difference between a waveform of electromotive force generated from inside and outside of an object region. Then, a numerical analysis and a phantom experiment were performed in order to confirm validity of the proposal method, and an experiment system was constructed. As results, it was indicated that image artifacts was reduced by the proposal method. However, since the image blurring was seen on the reconstructed image, the image resolution needs to be improved.
