Bloch image simulations for typical brain pulse sequences were performed using a GPU-installed gaming laptop PC and a numerical brain phantom. Artifact-free brain MR images were obtained by the Bloch image simulation using optimized numbers of subvoxels. Because the simulation times were the same order as the imaging time for the experiments, we concluded that the Bloch image simulator installed in an inexpensive gaming PC can be a powerful research tool for many MRI engineers and scientists.
