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.
