The dynamic bionic heart phantom comprises a bionic heart phantom, a control system, positive pressure devices and a negative pressure device； the bionic heart phantom comprises a water tank and a heart phantom arranged in the water tank, and the heart phantom is connected to the control system through four air pipes； the control system comprises an antimagnetic control device and a control PC, and the antimagnetic control device is composed of a measurement and control module, four proportional flow values, a power module and a magnetic shielding box； the positive pressure devices, comprising gas, gas cylinders and pressure reducing valves, are connected to two gas inlet interfaces of the control system respectively； and the negative pressure device comprises a vacuum pump and a negative pressure container, and the negative pressure container is connected to two gas outlet interfaces of the control system through air pipes. The dynamic bionic heart phantom is available for simulating an anatomical structure and motion characteristics of a human heart, has standard models of a normal heart and hearts with typical heart diseases, canoutput ECG signals synchronously, and is applicable to testing and evaluation on imaging quality of the MRI system.
