• Age: ≥ 14 years old,<80 years old, male or female not limited;
• Histopathological diagnosis of differentiated thyroid cancer;
• Surgical total or near total thyroidectomy;
• The surgery did not achieve R0 resection, and R1/ R2 resection was performed. The volume of residual tumor in R2 resected patients is less than 2cm3;

• There is distant metastasis;
• Previously received 131I treatment;
• Previously received or currently receiving targeted therapy, immunotherapy, chemotherapy;

• Other physical illnesses that affect patients' ability to receive standard treatment;
• According to the researchers' assessment, there may be other factors that could force the subjects to terminate the study, such as suffering from other serious illnesses (including mental illnesses) that require concurrent treatment, severe abnormal laboratory test values, family or social factors that may affect the safety of the subjects or the collection of experimental data;
• Individuals with claustrophobia who are unable to undergo radiation therapy;
