A non-ferromagnetic, multimodal two chamber moving heart phantom with applications to cardiac MR, echocardiography and Doppler imaging is presented. A biventricular structure is able to simulate the asymmetric LV motion and inter-ventricular displacements. A 10% solution of Poly Vinyl alcohol (PVA) was used as the main material. Freeze-thaw cycles were used to produce different elasticity, ultrasound attenuation and T1/T2 properties. An additional pathologic heart was made to model aneurysm. Three infarct mimicking inclusions of different elastic properties were added to simulate infarcted regions. Image series were acquired with Philips iE33 echocadriography workstation and 1.5 T Philips Achieva scanner.
