| Abstract: | Limited-angle (LA) dual-energy cone-beam CT (DECBCT) is a potential approach for DE imaging on existing CBCT scanners with a comparable data acquisition time and radiation dose to the conventional single-energy scan. However, the image reconstruction for LA-DECBCT is a challenging problem since the acquired DE projections do not meet Tuy's data sufficiency condition. In this work, we develop a diffusion model-based image reconstruction for LA-DECBCT with a projection-consistent mechanism to enforce data fidelity. © 2025 SPIE |
