Retrospective ECG-gated spiral scanning
- For "retrospectively ECG-gated spiral scanning" a continuous spiral scan is acquired with the ECG-signal recorded simultaneously.
- The acquired scan data is selected for image reconstruction with respect to a pre-defined cardiac phase.
- Similar to ECG-triggered sequential scanning a certain R-wave delay time defines the start point of data that is used for image reconstruction.
- It has several advantages over ECG-triggered sequential scanning as the continuous acquisition allows for reconstruction of overlapping slices. But due to the retrospective analysis of the ECG, the technique is less sensitive to arrhythmia.
