Comparison of User-Directed and Automatic Mapping of the Planned Isocenter to Treatment Space for Prostate IGRT

Figure 1

(a) Axial slice from the pCT showing planning prostate (white) and isocenter (black). (b) Corresponding slice from the tCT showing the prostate (black) segmented by automatic nonrigid model deformation. The rigidly mapped isocenter comes from translating the planning prostate (dim white) to the tCT. The nonrigidly mapped isocenter comes from applying the deformation matrix resulting from autosegmentation to the planned isocenter.
