“…To synchronise for cardiac motion, image acquisition takes place in either a retrospective ECG-gated or prospective ECG-triggered fashion. Scanning the entire heart in one gantry rotation has become feasible with the 320-row CT scanner [54]. This renders CTCA less vulnerable to artefacts due to breathing, irregular heart rhythm or higher rate [54].…”

“…Scanning the entire heart in one gantry rotation has become feasible with the 320-row CT scanner [54]. This renders CTCA less vulnerable to artefacts due to breathing, irregular heart rhythm or higher rate [54]. Also, temporal resolution has improved with faster gantry rotation times and the advent of dual source CT scanners [55], enabling the reconstruction of a cross-sectional image from a 90°instead of a 180°rotation.…”

“…Generally CCTA uses either helical or non-helical scanning; the two methods of non-helical acquisition are wide axial scan [1,2] and axial scan. Wide axial scan is available only on limited types of scanners.…”
