Partial-scan reconstruction Full scan reconstruction Average CT reconstruction CT noise 9.2 7.2 3.0 Date represent Standard Deviation (SD) within a ROI setup calculated in CT images of each reconstruction technique Image noise is related to CT temporal sampling scale: partial-scan reconstruction (0.33 s), full scans reconstruction (0.5 s), and average CT reconstruction (5 s)
