The Heart Phantom has completely anthropomorphic external and internal anatomy. The phantom is housed in a flexible PVC membrane, and embedded in a clear anechoic medium. All standard cardiac imaging planes are easily achieved. The Heart Phantom is ideal for teaching and developing ultrasound examination skills and techniques as well as demonstrating 3D ultrasound capabilities. Additionally this heart phantom is helpful for MRI cardiac applications development, MRI protocol management, and MRI 3D reconstruction.
