Description
Four-dimensional dose (4D dose) which uses deformable image registration (DIR) algorithm from four-dimensional computed tomography (4DCT) images can consider dosimetric effect by respiratory motions. The dose difference between 3D dose and 4D dose can be varied according to geometrical relationship between a planning target volume (PTV) and an organ at risk (OAR). The purpose of this study is to investigate the dose difference between 3D and 4D dose using overlap volume histogram (OVH) which is an indicator that quantifies the geometrical relationship between a PTV and an OAR. The tendency of dose difference variation was verified according to OVH. OVH is seems to be an indicator that has a potential to predict the dose difference between 4D and 3D dose
