Figure 1From: A comparative study on the volume and localization of the internal gross target volume defined using the seroma and surgical clips based on 4DCT scan for external-beam partial breast irradiation after breast conserving surgeryThe outline of GTVc, GTVs and GTVc + s. a. GTVc + s: the gross target volume delineated based on both seroma and surgical clips; b. GTVc: clips the gross target volume delineated based on surgical clips; c. GTVs: the gross target volume delineated based on the seroma; d. GTVc + s (yellow), GTVc (red) and GTVs (green) on the same lay of a 4D-CT data set.Back to article page
