PolyPose: Deformable 2D/3D Registration via Polyrigid Transformations
Vivek Gopalakrishnan, Neel Dey, Polina Golland
Determining the 3D pose of a patient from a limited set of 2D X-ray images is a critical task in interventional settings. While preoperative volumetric imaging (e.g., CT and MRI) p…

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…
