Method, which synchronize the data acquisition with the heartbeat or respiration.

See also Gating.

ECG trigger methods synchronize the heartbeat in order to minimize motion artifacts, whereat the r-wave is used as the trigger. ECG gating techniques are useful whenever data acquisition is too slow to occur during a short fraction of the cardiac cycle.

See also Triggering and Trigger Delay.

The trigger delay is the time after triggering at which data acquisition takes place.
