“…The automated broadening of the pulsing window to account for best image quality, but making the pulsing even less effective (Fig. 7), sustain the HRassociated findings described in the literature [28]. For any single-slice CT system using 4-64 slices inclusive for spiral coronary CTA, low HR not only provides good image quality but also low dose, because radiation dose savings at constant pitch are determined by the width of the pulsing window.…”

“…In patients with slow, regular heart rates, full cardiac acquisition using high-pitch prospective-ECG triggering can be obtained within one cardiac cycle at a low effective radiation dose (G1 mSv) [39][40][41]. Furthermore, the improved temporal resolution of DSCT has also been exploited to permit the use of prospective ECG-triggered scanning in patients with a higher heart rate [42], patients with arrhythmias [43], and in atrial fibrillation [44,45], while maintaining low radiation doses [46].…”
