4DRGS: 4D Radiative Gaussian Splatting for Efficient 3D Vessel Reconstruction from Sparse-View Dynamic DSA Images
4DRGS models vessels as 4D radiative Gaussians with a neural attenuation field and reconstructs 3D vessel volumes from sparse-view dynamic DSA images in about 5 to 13 minutes, matching or beating prior state-of-the-art quality.
