Researchers introduced X-Splat, a unified 3D reconstruction method that jointly models RGB and X-ray imagery using Gaussian splatting.

What it means

X-Splat is a novel research method that extends 3D Gaussian splatting—a technique for representing 3D scenes as a collection of Gaussian primitives—to simultaneously model both visible-light (RGB) photographs and X-ray projections. This allows a single set of Gaussian primitives to reconstruct an object's external appearance and its internal structure from the same representation, enabling new applications in non-destructive inspection, medical imaging, and cultural heritage. The paper was published on arXiv on October 19, 2026.

Accuracy & sourcesGrounded

The claim is the authors' own description of their preprint, making it an authoritative account of what X-Splat does. As a primary source (arXiv preprint 2610.23237), it is accurate about its own methodology and results, though the work has yet to undergo peer review. The project page and other coverage confirm the paper's existence and framing.
