Researchers have developed a new method for reducing metal artifacts in cone-beam CT (CBCT) scans using a splat-based approach. This technique integrates a polychromatic X-ray projection model and material-dependent attenuation profiles within a Gaussian Splatting framework to efficiently correct beam hardening artifacts. The method eliminates the need for manual metal masks or strong prior assumptions, jointly optimizing reconstruction parameters and X-ray spectral characteristics during training. The researchers also created a synthetic CBCT dataset generation pipeline and released new datasets to support the community, demonstrating superior performance over existing methods in artifact suppression and accuracy.
