Planning CT scan and differences between planning CT scans and fractional CT scans during the whole treatment course of one patient at center 2. The solid lines present the ROIs of planning and dash lines present the ROIs of fractional image. Target volume and OARs varies along with treatment, and the predicted probability of ARS increased. Using the best cut-off value of ROC curve, ARS was precisely classified. ARSpred: predicted ARS of the model. FH-L: left femoral head, FH-R: right femoral head
