Figure 14.

Axial images of the human head water phantom from MR experiments. 1^st and 2^nd columns: the image of each patch element; 3^rd and 4^th columns: the sensitivity maps of each element; 5^th column: the images reconstructed from the sum of squares method of full k-space; 6^th column: SENSE reconstructed images at acceleration factor of 2, average g-factor for each slice is shown beside the corresponding image; 7^th column: GRAPPA reconstructed images with 48 ACS lines at acceleration factor of 2. These parallel imaging results demonstrate the feasibility of the parallel traveling-wave MR imaging using the proposed patch antenna array.
