From: Motion compensated cine CMR of the fetal heart using radial undersampling and compressed sensing
Qualitative evaluation of compressed sensing. Reordered cine reconstructions of four retrospectively undersampled data sets (number of reconstructed spokes (NR) = 500, 750, 3000), shown at end-diastole, end-systole and as M-mode displays of signal along the white dashed lines. Cine movies corresponding to these reconstructions are available as supporting video S5. Short axis (a & b) and long axis (c & d) views are shown for two different volunteers. Arrows denote the thickness of the myocardium (a), fetal abdominal cavity (b), and pericardium (c & d), features that are degraded with increasing undersampling
