Abstract

In Magnetic Particle Imaging, superparamagnetic iron oxide nanoparticles are excited by an oscillating magnetic field that is generated by sending coils. In multidimensional set-ups, perfect geometrical decoupling cannot be achieved. Remaining coupling can distort the trajectory and introduce artefacts, thus active decoupling is introduced at costs of high power consumption. This work uses a device with active coupling control to investigate the influence of different coupling levels on the image reconstruction.
