Design outcomes

Primary

Measure	Time frame
Gating quality assessed by calculating jitter (in ms), performance index and propagation delay (in ms) from evaluating the recorded trigger timepoints against the manually annotated recorded ECG-trace. The annotation will be performed by two independent observers.	—

Secondary

Measure	Time frame
Image quality assessed semiquantitatively by two observers by using a visual rating scale	—
