Abstract:BackgroundDaily CTs generated by CBCT correction are required for daily replanning in online‐adaptive proton therapy (APT) to effectively deal with inter‐fractional changes. Out of the currently available methods, the suitability of a daily CT generation method for proton dose calculation also depends on the anatomical site.PurposeWe propose an anatomy‐preserving virtual CT (APvCT) method as a hybrid method of CBCT correction, which is especially suitable for large anatomy deformations. The accuracy of the hyb… Show more
