Three-dimensional versus four-dimensional dose calculation for volumetric modulated arc therapy of hypofractionated treatments

Respiratory motion is a non-negligible source of uncertainty in radiotherapy. A common approach is to delineate the target volume in all respiratory phases (ITV) and to calculate a treatment plan using the average reconstruction of the four-dimensional computed tomography (4DCT) scans. In this study...
