Exploring potential of different X-ray imaging methods for early-stage lung cancer detection

Purpose To explore the potential of X-ray imaging for early-stage lung cancer screening and to help finding an optimal lung cancer screening method. Methods Experimentally and simulatively comparing performances of different X-ray techniques (absorption-contrast imaging and phase-contrast imaging) for model lung cancer samples. Results Absorption imaging shows performance equal to or better than that of low-radiation dose. Conclusion Absorption imaging is still the most promising imaging method for early lung cancer detection.
