Objective: To explore the factors that affect the setting of radiotherapy in head and neck cancer and irradiation technique. Methods: Forty-eight patients with pathologically confirmed head and neck cancer were selected for routine radiotherapy. Two heads of technicians were fixed and measured with a head frame and a low-temperature thermoplastic mask. Results: After treatment, by CT, magnetic resonance imaging reexamination rate of 90%. Conclusion: The position assisting device ensures the stability and repeatability of position
