The goal of the work was to build a low cost cardiac phantom that mimics cardiac motion and measure thermometric profile based on applied B1+ fields during MR imaging. The cardiac motion inside the phantom was simulated using the mechanical gear setup. To obtain the thermometric profile of the cardiac phantom 12 probes were inserted into the phantom with required thermal insulation. The phantom also provides an opportunity to correlate local SAR findings with temperature measurements in the heart phantom.
