Figures & data
Figure 1. MVCT scan taken at the abdomen before treatment delivery. MVCT scan set was fused with treatment planning CT scan. The transverse sectional views are shown in (A) Tomo MVCT image and in (B) reference kVCT image. The fusion column (C) presents the kVCT in gray scale with the MVCT superimposed with a level of transparency in yellow. Similarly, the sagital sectional views and the coronal sectional views are shown in D, E, F and G, H, I respectively.
