Open Coil Arrangement for Interventional Magnetic Particle Imaging

Magnetic particle imaging (MPI) is a method to determine the spatial distribution of super-paramagnetic iron oxide particles (SPIOs) at potentially high sensitivity, high spatial and high temporal resolution [1,2,3]. For magnetic field generation and particle signal reception, electromagnetic coils are used. In their paper [1], Gleich and Weizenecker proposed a tube-like scanner setup as it is illustrated in Fig. 1. So far, a scanner device has been implemented, which fits a mouse, but the aim is to scale it up to finally image a human body. In many cases, there might be the need to access the patient while acquiring images. The aim of this work is to find a new coil geometry, which provides this additional feature without or with only little loss in image quality and only little additional expenses.
