Rapid patient-specific neural networks for intraoperative X-ray to volume registration
Vivek Gopalakrishnan, David-Dimitris Chlorogiannis, Andrew Abumoussa +6
Advanced navigation techniques in image-guided interventions and surgical robotics require the rapid and precise alignment of 3D preoperative volumes (e.g., CT, MRI) to 2D intraope…
When Experts Disagree: Characterizing Annotator Variability for Vessel Segmentation in DSA Images
M. Geshvadi, G. So, D. D. Chlorogiannis +12
We analyze the variability among segmentations of cranial blood vessels in 2D DSA performed by multiple annotators in order to characterize and quantify segmentation uncertainty. W…
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…
