Magnetic resonance imaging (MRI)-compatible pulsatile flow and pressure circulation system. (a) MRI-compatible circulation system composed of a left atrium chamber, mitral valve model, left ventricle model, aortic valve model, aortic arch model, compliance chamber, and resistive unit. The pneumatic control system, connected via tubing to a left ventricle model, is placed outside the magnetic resonance room. (b) The setup on the magnetic resonance examination table. (c) Aortic arch model incorporating an aortic valve model.
