Conclusion: This study demonstrates that VFIT-based projection interpolation can enable substantial CBCT dose reduction while maintaining image quality and suggest a promising approach for reducing secondary cancer risks in CBCT-guided radiotherapy.

Keywords: CBCT, dose reduction, projection synthesis
