Key points: radiotherapy for superficial tumors is often encountered clinically, such as after modified radical surgery for breast cancer, skin cancer, soft tissue sarcoma, parotid gland cancer, Merkel cell carcinoma, superficial lymph node metastasis, etc. Compensation technology is required for both conventional radiotherapy and intensity-modulated radiotherapy.

 

 

Usually, when patients undergo radiation therapy, a positioning membrane is used to improve the treatment effect, which can ensure the accuracy of the irradiation site.

 

 

 

Radiation therapy is a local treatment method that uses radiation to treat tumors. Positioning film is a special plastic used to assist in fixing the patient's position and improve the therapeutic effect of radiation therapy. During radiation therapy, positioning film can help doctors and physicists accurately transmit the radiation beam to the tumor

 

 

 

Tumor, ensure the accuracy of the irradiated area.
