Without using ECG input signals or processor intensive correlation, cyclical timing is determined from ultrasound data. Cyclical timing includes determining the time of end diastole, time of end systole or heart rate. The ultrasound data is reduced, such as by projecting each frame of data onto two axes. For projection, data is summed along each dimension. The location associated with the maximum variance through the sequence is identified from the projected data. The ultrasound data associated with the location is used to identify cycle timing information, such as to provide a waveform representing the cycle. Lines from different frames of data in the sequence are also used to generate an image. The image shows cycle timing information.
