New splat-based method reduces metal artifacts in CT scans

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a new method for reducing artifacts in cone-beam computed tomography (CBCT) scans, particularly those caused by metal implants. This novel approach utilizes a physics-inspired, self-calibrating technique integrated within a Gaussian Splatting framework. It addresses beam hardening artifacts by incorporating a polychromatic X-ray projection model and material-dependent attenuation profiles, eliminating the need for manual metal masks. The method also optimizes X-ray spectral characteristics during training and has demonstrated superior performance over existing state-of-the-art methods in artifact suppression and reconstruction accuracy.
