which is reserved for labeling of the cardiac phase
and heart rate in beats per minute (bpm).
Example of a preview series at the correct anatomical
level (mid RCA), demonstrating the importance of
optimized phase setting. Patient with an average
heart rate of 63 bpm.
Left: 57%, mid: 61%, right: 65% relative delay.
The image at 61% relative delay shows the least
motion artifacts. In this example, even a slight change
of the phase setting from 61% to 65% deteriorates
image quality.
