Fig. 9From: Cone-beam CT reconstruction for non-periodic organ motion using time-ordered chain graph modelComparison of motion artifact from rectum of patient A. The yellow box on image a shows the enlarged area of the axial images of patient A, the fourth phase. The images b, c, d and e are reconstructed using TVCS (360°), TVCS (200°), PICCS (90°) and the TCGM (90°). The display range is [0.019 0.022] mm −1 Back to article page
