Reconstructed CT images dataset

Reconstructed CT images are derived from X-ray absorption-contrast CT（XACT）, dual-energy CT（DECT）, and X-ray phase-contrast CT（XPCT） through numerical simulation and Monte Carlo simulation. Based on these dataset, reconstructed CT images can be obtained directly.They serve as the most fundamental and critical basis for subsequent comparative evaluation.Based on this dataset, the comparative evaluation of the three imaging methods can be conducted systematically, providing guidance for the application of XPCT in medical settings.
