ABSTRACT:
A dynamic phantom system and method utilizing a phantom device for simulating operation of a heart. The phantom device comprises first and second rotatable ellipsoids having first and second axes of rotation for simulating an atrium and a ventricle, respectively, of the heart, and a motor for rotating the first and second rotatable ellipsoids in unison to simulate the operation of the heart. The axes of rotation of the first and second rotatable ellipsoids are mutually perpendicular. A trigger circuit is further provided for issuing a trigger pulse in response to each rotation of the first and second rotatable ellipsoids. An attenuator is also provided for simulating ejection fraction of the heart. The dynamic phantom device is especially useful in testing camera-computer combinations employed for heart imaging and monitoring, so as to evaluate the quality of operation of the camera-computer combination.
