Comparison of User-Directed and Automatic Mapping of the Planned Isocenter to Treatment Space for Prostate IGRT
Figure 8
Color-coded difference maps for points in the tCT nonrigidly registered to the pCT using FEM and models. In the prostate ROI the agreement between the two methods is ~1 mm along the and axes and ~2 mm along the axis. The larger difference along the axis is attributed to the 3 mm slice thickness.
