Figure 3From: Adequacy of inhale/exhale breathhold CT based ITV margins and image-guided registration for free-breathing pancreas and liver SBRTStatistics for bone to fiducial shifts. a-c. Histograms of bone-marker discrepancies for AP, SI, and RL directions, respectively. Gaussian fits of the histograms give average (μ) and standard deviation (σ) values in each of the three directions. d-f. Bar plots of % of fractions that has bone-marker shifts in <0.3 cm, 0.3 - 0.5 cm, 0.5 - 1 cm, 1 - 1.5 cm, and >1.5 cm for AP, SI and RL directions.Back to article page
