Respiratory triggering (Rtr) uses a closed bellows strapped around the patient’s chest, which expands and contracts as the chest rises and falls. The system monitors the patient’s breathing pattern and displays a “bar” beneath the waveform to indicate the scan’s acquisition portion of the respiratory interval. It reduces respiratory artifacts by synchronizing image data collection with the respiratory cycle, acquiring images when the chest wall is in the same position.
