Reconstructions of bins 1, 2, and 3 with 46, 33 and 27 radial profiles (corresponding to undersampling factors R of 11, 15 and 19, respectively). a: Zero‐filled reconstructions. b: Iterative SENSE used in 16, significant aliasing remains. c: TV‐SENSE, most aliasing is eliminated. d: k‐Space sampling locations in the phase encoding plane for bins 1, 2, and 3. e–h: Motion estimation errors (in voxel units) between neighboring bins for TV‐SENSE and iterative SENSE bin reconstructions for two volunteers. Color coded motion estimation errors are overlaid on the anatomical reconstruction. Iterative SENSE motion estimation (f–h) shows increased local errors, whereas TV‐SENSE provides more reliable motion estimation (e–g).
