A patch antenna was used to generate a traveling wave inside the bore in order to obtain images of regions outside the human brain at 7 Tesla, focusing on the left carotid artery by means of a local receiver coil. Both GRE and SE images were obtained from healthy volunteers demonstrating the performance of the setup.
