Approach: The scatter correction method, named e-Grid, which was initially applied to dual-layer flat-panel detector (DLFPD)-based CBCT imaging, was tested for its performance in PCD-CBCT imaging. Benchtop PCD-CBCT imaging experiments were conducted to verify the effectiveness of the e-Grid method. Additionally, quantitative metrics were measured from these experimental results.
