FIG. 6. — The WEPL errors between the CT_ref and CBCT_ap images in special cases. [(a) and (b)] absolute error (in mm and percentage, respectively) in the situations of anatomic changes between CT and CBCT scans; [(c) and (d)] absolute error (in mm and percentage, respectively) for the cases of misregistration of a priori image. The result demonstrates the feasibility of CBCT_ap in a practical application of APT. The error bars represent one standard deviation.
