Analysis
This paper addresses the critical problem of metal artifacts in dental CBCT, which hinder diagnosis. It proposes a novel framework, PGMP, to overcome limitations of existing methods like spectral blurring and structural hallucinations. The use of a physics-based simulation (AAPS), a deterministic manifold projection (DMP-Former), and semantic-structural alignment with foundation models (SSA) are key innovations. The paper claims superior performance on both synthetic and clinical datasets, setting new benchmarks in efficiency and diagnostic reliability. The availability of code and data is a plus.
Key Takeaways
- •Proposes a novel framework (PGMP) for metal artifact reduction in dental CBCT.
- •Combines physics-based simulation, deterministic manifold projection, and foundation model priors.
- •Claims superior performance and sets new benchmarks in efficiency and diagnostic reliability.
- •Provides code and data for reproducibility.
