Optimizing Cardiac Dose Sparing in Lung Cancer SBRT Through 4D-CT-Based Respiratory Phase Selection

Key Points

• Enhanced cardiac dose sparing was achieved through optimization techniques in lung cancer patients undergoing SBRT.
• Key metrics showed notable reductions in cardiac exposure during the SBRT procedure, ensuring improved safety outcomes.
• Observational analysis across lung cancer cases indicated promising improvements with 4D-CT-based respiratory phase selection.
• This approach highlights the potential for tailored radiation therapy strategies, though further validation in larger cohorts is needed.
