Development of motion compensation strategies is challenging, especially when involving volunteer measurements due to high demands to subject compliance and low reproducability. In this work a human shaped torso phantom, capeable of simulating respiratory motion of a left ventricle phantom including blood flow simulation is presented. A tracking algorithm is applied in postprocessing to acquired images containing simulated respiratory motion. Comparison to motion tracking data from an external sensor show good agreement proving the setup to be an environment with high reproducability and hence ideal for the purpose to develop and evaluate motion compensation strategies.
