Accuracy of registration techniques and vascular imaging modalities in fusion imaging for aortic endovascular interventions: a phantom study

CVIR Endovascular

Table 1 Comparison of different registration techniques and imaging modalities

Results for seven different c-arm angulations and both imaging modalities in the thorax and the abdomen are given. For each angulation, the mean ± standard deviation of all measurements along the vessel’s course was calculated. Significance was accepted for p < 0.05; significant differences are underscored in dark grey. Overall, 3D-3D registration was more accurate than 2D-3D registration. Furthermore, a decrease in registration accuracy was observed for c-arm angulations of 30° to 60° and − 30° to − 60°
