Comparative example showing axial and sagittal images of a 1-min CBCT before motion correction (NoCorr CBCT), after motion correction [RMC-CBCT(tx)] derived from RCCT at treatment, and gated CBCT(gated-CBCT). Areas of tumor and diaphragm that are blurred in the NoCorr CBCT but show reduced blurring in the RMC-CBCT and gated CBCT. All images shown are mapped to a window-level of −250 HU and a window width of 900 HU.
