From: High performance MRI simulations of motion on multi-GPU systems
Series of images of the heart model during motion, obtained after a 1–1 SPAMM preparation, producing saturation bands. Note the gradual loss of contrast between the bands and myocardium throughout the cardiac cycle due to T1. Kernel execution time on the 4×C2075 system: approximately 7 hours. The entire 3D object was simulated; not just the slice of interest. (Total number of tissue isochromats 7 632 792, total number of time-steps 11 943 600, k-space matrix 128 × 128, FOV 15 cm × 15 cm, slice thickness 10 mm, 100 phases per cardiac cycle and 1 view per segment).
