Transverse slice of patient 1 after 4D-simulation of a single fraction for different motion mitigation approaches: (A) no motion mitigation, (B) 2x-layered rescanning, (C) 6x-layered rescanning, (D) 2x breath-sampled rescanning, and gating (E). (F) shows the nominal, i.e., expected, distribution without any motion, simulated on the planning CT. The color bar is in percent of prescribed dose, the contours represent the GTV (orange/inner contour), and the IGTV (magenta/outer contour).
