Influence of trigger type, tube voltage and heart rate on calcified plaque imaging in dual source cardiac computed tomography: phantom study.

In our experimental setup there were no significant differences regarding vessel diameter, plaque diameter and grade of stenoses between the different heart rates (50, 70, 90) although we found a slight trend to larger deviations of the measured parameters comparing the 50 and the 90 bpm data (Table 2 ).
