Slice scanning mode for traveling wave MPI

Abstract

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 tslice=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.
