Claim Text:
1. A system for providing an image acquisition trigger signal compensated for signal processing time delay, comprising: a processor programmed to; receive waveform signal data representing electrical activity of a patient heart over at least one heart beat cycle; detect a particular point associated with a particular signal portion within successive heart beat cycles of said signal data; provide a first timing adjustment signal in response to detected change in time of occurrence of the detected particular point in said successive heart beat cycles; provide a second timing adjustment signal in response to comparison of relative timing of said image acquisition trigger signal and said detected particular point in at least one of said successive heart beat cycles; provide a third timing adjustment signal in response to comparison of relative timing of said image acquisition trigger signal and a timing signal associated with time of acquisition of an image received from an image acquisition system; an output processor configured to generate said image acquisition trigger signal in response to said first timing adjustment signal and said second timing adjustment signal; and wherein said output processor generates said image acquisition trigger signal by summing time adjustments associated with said first timing adjustment signal, said second timing adjustment signal and said third timing adjustment signal to provide a predicted time of acquisition of an image within a heart cycle.
