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.
