Magnetic particle imaging (MPI) is a new tomographic imaging modality first presented in 2005. It directly and quantitatively images iron-oxide nano-particle concentrations. By means of a broadband data acquisition, MPI also is very fast imaging modality allowing real-time volumetric imaging. After a motivation for broadband reception, this abstract describes the inherent challenges of and a technical solution for a low-noise broadband receive amplifier. This new amplifier is part of the current pre-clinical MPI demonstrator with ~12cm bore size.
