摘要

这个原型系统已经产生了高质量的图像，其空间分辨率与老鼠大小的fov的理论预测分辨率非常相似。我们对塑料和生物成像幻影以及离体小鼠(未显示)进行了成像。一些早期图像如下图1b-c所示。成像时间与微mri相当:完整的小鼠和大鼠图像(高达12厘米× 5厘米× 5厘米)每张图像需要2-5分钟。

A 7 T/M 3D X-space MPI mouse and rat scanner

This prototype system has already produced high quality images with spatial resolutions very similar to the theoretically predicted resolution across mouse and rat sized FOVs. We have imaged both plastic and biological imaging phantoms, as well as ex vivo mice (not shown). Some early images are shown below in Fig. 1b-c. Imaging times are comparable to micro-MRI: full mouse and rat images (up to 12 cm × 5 cm × 5 cm) require between 2-5 minutes per image.
