Statistics for CBCT to kV shifts. a-c. Histograms of differences between CBCT and kV 2D images for AP, SI, and RL directions, respectively. Gaussian fits of the histograms determine the average (μ) and standard deviation (σ) for each of the three directions. d-f. Bar plots of% of fractions that has CBCT to kV 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.
