Overview
- X2-Gaussian reconstructs dynamic CT scans with 4D radiative Gaussian splatting
- Uses continuous-time representation instead of discrete time steps
- Combines benefits of 3D Gaussians with X-ray physics
- Achieves state-of-the-art results on dynamic CT reconstruction
- Handles motion blur, sparse views, noise, and limited-angle problems
- Up to 13× faster reconstruction than previous methods
Plain English Explanation
Imagine trying to take an X-ray video of a moving object. Traditional methods struggle because they need to capture many images very quickly, leading to blurry or incomplete results.
X2-Gaussian solves this problem by creating a continuous 4D model (three dimensions of space p...
