摘要

图1B中所示的样品包含一个内径为860 μm的管,管内填充未稀释的Resovist®(拜耳-先灵,德国),嵌入丙烯酸玻璃。每个切片的采集时间为tslice=1/f1,取4000个平均值,f1=920 Hz,总采集时间为t=4000/f1= 4.35 s。本征空间分辨率由设置给出,并计算为z方向2 mm和x方向4 mm。反卷积图像(见图1B)显示了良好的一致性,并证明了成像研究的可行性,例如在临床前背景下,基于TWMPI。

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 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.
