Slice scanning mode for traveling wave MPI

The sample shown in fig. 1B contains a tube with an inner diameter of 860 μm filled with undiluted Resovist® (Bayer-Schering, Germany) embedded in acrylic glass. The acquisition time for one slice is t_slice=1/f₁, with 4000 averages and f₁=920 Hz the overall acquisition time is t=4000/f₁=4,35 s. The intrinsic spatial resolution is given by the setup and was calculated to be 2 mm in z- and 4 mm in x-direction. The deconvoluted image (see fig. 1B) shows a good agreement and proves the feasibility of imaging studies, e.g. in pre-clinical context, based on TWMPI.
