Abstract
Two or more temporal indicators are used for interleaving frames from a plurality of physiological cycles. For example, frames of one cycle are separated from the frames of another cycle based on an ECG signal. Data representing an imaged region for each of the frames is then used for temporally aligning the frames. For example, average velocity waveforms calculated from the frames of each of the cycles are fitted together. The temporal position of each of the frames within a base physiological cycle is determined based on the fitting. The interleaved frames provide a higher effective frame rate with improved temporal resolution which is based on the accurate interleaving of the data from the plurality of physiological cycles. Course alignment is provided using one event or temporal indicator. A more refined temporal alignment is provided in response to a second temporal indicator.
