Patient Body Motion Correction: (a) Mid-ventricular short-axis slice from initial-rest study acquired without intentional patient motion and reconstructed with 30 iterations of MLEM. (b) Short-axis slice from second-rest study acquired with intentional patient motion and reconstructed with 30 iterations of MLEM. Notice translated location of heart and significant artifact. (c) Short-axis slice from second-rest study acquired with intentional patient motion and reconstructed with 40 iterations of MC-MLEM. (d) Short-axis slice from second-rest study acquired with intentional patient motion and reconstructed with 20 iterations of MC-MLEM. We applied clinical-levels of 3D post-reconstruction smoothing.
