The development of novel acquisition and reconstruction techniques for MRI relies on realistic computer simulations. In case of cardiac applications, respiratory motion and cardiac contraction add to the simulation complexity. In this work, a framework for realistic numerical simulation of cardiac MRI is proposed. Anatomy and motion are provided by the XCAT phantom, which is based on the Visible Human project from the National Library of Medicine. The MR phantom is generated on top by simulating dynamic contrast, multiple receive coils, measurement noise and k-space trajectories. Showcase applications of image reconstructions from undersampled data are presented.
