Abstract:Objective To discuss the feasibility of CBCT (Cone Beam Computerized Tomography) in
detecting the volume change of the bladder and cervical target in image-guided radiotherapy for cervical
cancers. Methods Ten cervical cancer patients were selected and asked to keep their bladders full. Then,
the outline of bladders and cervical targets was made in the CT simulation and CBCT images which
were obtained in the same window width and position. The volume of the bladder and cervical targets
was calculated by the Varian Planning System so as to compare the volume changes in each radiation as
well as the relative volume changes (the proportion of the contoured organ volume in CBCT to that in
CT) in bladders and cervical targets.
