2D imaging with a single-sided MPI device

This paper presents 2D images that have been measured successfully with a single-sided magnetic particle imaging (MPI) scanning device. This provides proof that multidimensional single-sided MPI is possible. At the moment, the highest achieved penetration depth is about 10 mm. The penetration depth is limited by the inhomogeneous magnetic fields, which are caused by the asymmetric coil assembly. Besides, a measurement width of 30 mm is possible in y-direction at the cost of a reduced accuracy. The next steps aim to improve the signal to noise ratio, to calculate the resolution and the sensitivity of the single-sided scanner.
