Lung cancer remains the leading cause of death in the United States, necessitating effective treatment options. Radiation therapy has emerged as a prominent treatment modality, with stereotactic body radiation therapy (SBRT) gaining popularity. However, the use of linen coverings during treatment should be considered when calculating skin dose. This study aims to evaluate the impact of linen materials on skin dose during SBRT lung treatments. Understanding the dosimetric effects of linen coverings is critical for optimizing treatment outcomes and ensuring patient safety.


This study aimed to evaluate the effects of linen materials on the skin dose during stereotactic body radiation therapy (SBRT) for lung cancer patients. The researcher used a RANDO phantom to create seven tumors and calculated the dose for an SBRT treatment with different linen coverings (gown, sheet, and blanket). The plans were generated using the Varian Eclipse workstation following the RTOG 0813 protocol.


The results showed that all linen coverings increased the skin surface dose compared to the no-covering plan. The skin maximum dose, dose to 0.03cc, and dose to 0.3cc were all significantly higher when linen coverings were present. The gown and sheet coverings had similar effects on the skin dose, while the blanket covering showed the highest increase in skin dose.


Linen coverings, such as gowns, sheets, and blankets, used during stereotactic body radiation therapy (SBRT) for lung cancer treatments result in an increase in skin dose. The study found significant evidence of increased skin dose when linens interfered with the radiation beam. This dose increase could lead to skin reactions and impact patient tolerance to treatment. The research suggests that radiation oncology departments should avoid using linen coverings during SBRT lung treatments to ensure optimal treatment outcomes and minimize potential side effects. Healthcare providers can prioritize patient safety and comfort during radiation therapy by understanding the impact of linen material on skin dose.
