Magnetic particle imaging (MPI) is a technology that directly detects the nonlinear response of magnetic nanoparticles (MNPs). It has garnered significant attention in medical imaging. MNPs are saturated except near a specific point known as the field-free region, established by applying a static magnetic field [1]. Recent research has underscored using the field-free line (FFL) method for scanning the field-of-view to enhance MPI sensitivity [2-4]. This paper reports on a performance evaluation of an MPI system employing two pairs of electromagnets capable of scanning the FFL by finely adjusting the distribution of current flowing through each electromagnet.
