    The study integrates four-dimensional computed tomography (4DCT) ventilation imaging into radiotherapy planning for lung cancer management.

  • 2

    Functional planning using 4DCT significantly reduces radiation doses to functional lung volumes while maintaining target coverage.

  • 3

    Among the radiotherapy techniques, functional volumetric modulated arc therapy (f-VMAT) shows superior dosimetric outcomes compared to f-IMRT and f-hybrid IMRT.

  • 4

    Functional planning increases radiation doses to organs at risk, but these increases are not statistically significant across the techniques.

  • 5

    The study highlights the potential of 4DCT ventilation imaging to improve lung cancer treatment outcomes by addressing lung function heterogeneity.
