advanced heart tissue phantom as a reference for MRI sequence evaluation

For evaluating dynamic cardiac MR imaging sequences a advanced heart simulator has been built. The phantom uses a polyvinyl alcohol (PVA) based tissue model and is able to simulate heart beat and breathing motion. The device is specially designed to fit into a clinical environment. No modifications of the MRI system are required that could cause the loss of approval. As the phantom feeds trigger signals directly over the physiology board all evaluated sequences can be transferred directly to clinical examination without the need of sequence reprogramming. Its design allows the use of cardiac anterior and posterior dedicated receiver coils.
