In the past, MR simulations were usually confined to incorporation of simplified anatomical models of limited realism and/or simulations of basic MR physics concepts only. The purpose of this study was the incorporation of the XCAT anatomical phantom in MRISIMUL, a high performance multi-GPU simulation platform. Two different CMR applications were studied: the first for heart morphology evaluation and the second for T1 mapping of the heart. Results showed that the incorporation of realistic human anatomical models in a high performance MR simulation platform may benefit the design and optimization of MR protocols and pulse sequences in the future.
