Joint-decoupled iterative CBCT reconstruction with hybrid scatter estimation and voxel-adaptive beam hardening correction
A physics-driven iterative framework rooted in the polychromatic Polyquant attenuation model is proposed, which decouples scatter and beam hardening artifacts by establishing an optimization loop between scatter estimation and relative electron density (RED) reconstruction.
