GE images of the heart motion model. (A) Application of the gradient echo pulse sequence on the heart model under no motion. No artifacts observed. (B) Application of the gradient echo pulse sequence on the heart motion model with no triggering. Phase direction artifacts are observed. (C) Application of the CINE GE pulse sequence triggered to the heart motion model for different combinations of phases per cycle and views per segment: 100 phases and 1 view per segment (1st row), 50 phases and 2 views per segment (2nd row) and 20 phases and 5 views per segment (3rd row). (Total number of tissue isochromats 7632792, total number of time-steps for GE: 1280000, for CINE 1st row: 22080000, for CINE 2nd row: 11040000, for CINE 3rd row: 4480000, k-space matrix 256 × 256, FOV 36 cm × 27 cm, slice thickness 10 mm, kernel execution time on the 4×C2075 system for GE: 36 min, for CINE 1st row: 887 min, for CINE 2nd row: 434 min, for CINE 3rd row: 175 min). The entire 3D object was simulated; not just the slice of interest. Contrast has been exaggerated to visualize the residual artifact in the noise floor.
