A computer‐controlled motion stage was designed to facilitate motion studies and simulations of cardiac magnetic resonance (MR) experiments. The stage was constructed to move a phantom of up to 6 kg at velocities up to 15 cm/sec along a two‐dimensional trajectory within an MR scanner. The operation of the motion stage was validated and found to be accurate to within 0.08 cm in displacement and 1.5 cm/sec in velocity (root‐mean‐square error). No image degradation was observed.J.
