Figure 1. Deformable Registration for ART.

Figure 1

Our ART process starts with rigid alignment between the reference planning CT and the daily in-room CT (left and middle). The planning contours are overlaid to the daily CT to verify setup accuracy and to evaluate changes in anatomy relative to baseline. If changes are significant, as illustrated in the middle picture, a deformable image registration can be performed to propagate original planning contours onto current anatomy. Final deformed contours are shown on the right.
