39 Evaluation and comparison of CT-CBCT deformable image registration quality of two software for cervical cancer treatment

Introduction. During radiotherapy for cervical cancer, anatomical modifications can occur. Daily cone beam CT (CBCT) acquired for positioning issue, could be used to calculate the daily dose. Besides, using a cumulative strategy, it might also allow to calculate the delivered dose during treatment. For this purpose, a CT-CBCT deformable image registration (DIR) is required. The aim of this study was to investigate the quality of DIR for two software.
