"Radiation source: 6MV photon linear gas pedal is used. Position immobilization: supine position, hands up, vacuum bag or styrofoam immobilization.~Radiotherapy plan design: 4DCT positioning, radiotherapy plan design at 20% respiratory time-phase CT, isocentric irradiation, IMRT or VMAT design.~Definition of target area:~Gross tumor volume (GTV) includes the primary tumor in the lung, excluding lymph nodes. Internal target volume (ITV); Internal target volume (ITV) is formed by the fusion of 10 respiratory phases of GTV; Planning target volume (PTV) is formed by expanding the ITV by 0.5 cm in all directions."
