FIG. 4.

Schematic illustration of data segments in parallel geometry used for ECG-synchronized DSCT image reconstruction. Due to the mechanical assembly, the minimum data interval per measurement system is ${\theta }_{\mathrm{rec}}=\pi ∕2$ in parallel geometry (indicated by dashed lines). The data interval for each measurement system can be increased (indicated by solid lines) to trade-off temporal resolution for dose accumulation in order to reduce the image noise for obese patients.
