Differentiable Voxel-based X-ray Rendering Improves Sparse-View 3D CBCT Reconstruction

Mohammadhossein Momeni, Vivek Gopalakrishnan, Neel Dey +2

We present DiffVox, a self-supervised framework for Cone-Beam Computed Tomography (CBCT) reconstruction by directly optimizing a voxelgrid representation using physics-based differ…
