Spatiotemporal Distillation via Recurrent Bottlenecks for Aortic Tracking

Cardiac cine-MRI serves as a direct visual indicator of cardiovascular hemodynamics by capturing the continuous wall motion of the aorta. Quantifying these dynamic structural changes across the cardiac cycle is essential for measuring aortic distensibility, a primary marker of arterial stiffness. However, standard 2D s...

A Joint 2D-3D Statistical Shape Model for Orthopedic Reconstruction

Three-dimensional femoral reconstruction from radiographs supports surgical planning, implant sizing, and post-operative follow-up, but remains ill-posed as X-ray projections discard depth information. Existing methods often incorporate a 3D statistical shape model (SSM) as a shape prior to guide reconstructions toward...

Shape-guided Gaussian Splatting for Sparse-View X-ray 3D Reconstruction

A shape-guided Gaussian splatting framework for sparse-view X-ray 3D reconstructions that ensures anatomically consistent reconstruction and improves PSNR by 2.83 dB over a state-of-the-art Gaussian splatting baseline with as few as 5 views is proposed.
