The intensity fluctuations of the radiation from a beating heart filled with radioactively labeled blood is analysed in such a way that the stroke volume and thus the cardiac output can be determined. The method is independent of any background radiation and irregularities of the heart rate. Further features are the speed of the method and the immediate imaging of the kinetics of the heart wall.
