Optimizing head and neck cancer treatment: Insights into immobilization and setup accuracy in IMRT

• IMRT minimizes exposure to surrounding healthy tissues by providing high-dose precision that follows the outlines of the tumor. • The use of 5-point thermoplastic masks assures immobility of the patient, which is essential for precise therapy. • The accuracy of therapy and setup errors are affected by variables including BMI, neck supports, and the presence of radiation therapists. • Standardized treatment processes and excellent communication tactics decrease setup mistakes while increasing patient comfort and consistency.
