FIG. 3

Ex vivo experiment with retrospective acceleration for a representative slice. The fully sampled data (R=1) was retrospectively undersampled by factors R=4, 8, and 12 using the Poisson-disk pattern, and reconstructed using the SPARSE-SENSE algorithm in MATLAB. Adequate image quality can be obtained up to R=8. R=12 shows residual aliasing artifacts (arrow) and slight blurring in the region around the metal implant (zoomed images in the bottom row). Note that these images were reconstructed offline without gradient warp correction.
