Figure 9

All DDCs from all observers with the body phantom with 27 cm effective diameter. Measurements which were done with the DDC module with contrast agent are shown by the blue curve for a tube voltage of 100 kV and by the orange curve with 120 kV. The results from the native DDC module are represented by the green curve (100 kV tube voltage) and red curve (120 kV tube voltage). The error bars show the standard deviation of all observers; these error bars are large since a large number of CT units and different CTDI values are included. A logarithmic fit was applied according to Eq. (1).
