Abstract
A method includes obtaining an electrocardiogram (ECG) signal during a scan of a heart of a subject with a CT scanner. The method includes calculating temporal R-R electrocardiogram interval measurements from the ECG signal. The method includes monitoring whether any irregular cardiac cycles are detected in the temporal R-R electrocardiogram interval measurements. The method includes determining whether an initial Z coverage of the scan is sufficient for obtaining an artifact free image of the heart at a target phase when one or more irregular cardiac cycles are detected. The method includes determining a required Z coverage to obtain the artifact free image of the heart at the target phase when the initial Z coverage is not sufficient. The method includes initiating a rescan of the heart to obtain the required Z coverage while continuing both to obtain the ECG signal and to monitor for any irregular cardiac cycles.
