Data rebinning based decoupling of pFOV overlap scanning in magnetic particle imaging

Magnetic particle imaging (MPI) is rapidly developing as a novel biomedical imaging technique. Due to the safety constraints of bioelectromagnetic stimulation, the partial Field of View (pFOV) scanning approach has been widely used in MPI devices towards small animals and human scales. pFOV scanning has variable degrees of overlap between neighbouring pixels, which may lead to signal aliasing and blurring on harmonic imaging by Fourier transformation. In this paper we propose a data rebinning method for decoupling overlap scanning under a continuous pFOV scanning process. The results show that data rebinning as a digital signal preprocessing technique has the potential to improve the spatial resolution of imaging.
