Abstract
A method of cardiac gating for use in an imaging apparatus includes monitoring a patient's cardiac cycle, and determining a cardiac cycle time for the patient. A desired cardiac phase of interest is selected, and a delay from a reference point in the cardiac cycle is determined. The delay is a function of the selected cardiac phase and the cardiac cycle time. Finally, the selected cardiac phase is located in the cardiac cycle using the delay. This cardiac gating method compensates for non-uniform changes in the patient's cardiac cycle corresponding to a non-uniform distribution of cardiac phases in the patient's cardiac cycle.
