Diagram of signal pre-synchronization. ECG signal (a), corresponding k-space profile acquisition diagram (b), and CSG signal (c) are presented. The red and blue points represent the ECG and CSG triggers, respectively. Note that the black points of the signal curves represent the monitored ECG signal data (a) and derived CSG signal data (c).
