The Missing Views Were Not the Main Artifact
A reconstruction study traced streaks and strips chiefly to small pose errors in the scanner geometry, then refined that geometry alongside the image.
Summary
A reconstruction study traced streaks and strips chiefly to small pose errors in the scanner geometry, then refined that geometry alongside the image.
A study of splat-based sparse-view computed tomography argues that acquisition-pose errors, more than sparse sampling alone, drive prominent streak and strip artifacts. The authors jointly optimized the reconstruction and geometric parameters with gradients, reporting improved results after pose refinement across their tests. The work appears in the CVPR 2026 record and is a reconstruction-method study, not a clinical trial or claim about a particular scanner or patient.
