To explore the variations of the gross tumor volume (GTV) from different three-dimensional computed tomography (3DCT) scan modes and the consistency of internal target volume (ITV) between different 3DCT, cone-beam computed tomography (CBCT) and four-dimensional computed tomography (4DCT) scan, a study using a motion phantom simulating sinusoidal movement was conducted. For three 3DCT scan modes the GTV was contoured, and ITV was generated on the basis of GTV with a 10-mm margin while ITV and ITV with a 0-mm margin on the mo
