OsteoFlow: Lyapunov-Guided Flow Distillation for Predicting Bone Remodeling after Mandibular Reconstruction
Hamidreza Aftabi, Faye Yu, Brooke Switzer +6
Predicting long-term bone remodeling after mandibular reconstruction would be of great clinical benefit, yet standard generative models struggle to maintain trajectory-level consis…
Patient-Specific Optimization for Mandibular Reconstruction Planning with Enhanced Bone Union
Hamidreza Aftabi, John E. Lloyd, Amanda Ding +4
Mandibular reconstruction with vascularized bone grafts is complicated by donor-host nonunion, and current virtual surgical planning produces a geometric plan rather than a configu…
SurgCalib: Gaussian Splatting-Based Hand-Eye Calibration for Robot-Assisted Minimally Invasive Surgery
Zijian Wu, Shuojue Yang, Yu Chung Lee +3
We present a Gaussian Splatting-based framework for hand-eye calibration of the da Vinci surgical robot. In a vision-guided robotic system, accurate estimation of the rigid transfo…
SemICP: Semantic Non-Rigid Point Cloud Registration with Elastic Energy Regularization
Wanwen Chen, Qi Zeng, Carson Studders +6
Purpose: Accurate point cloud registration is essential in computer-aided interventions (CAI) to align multi-modal medical images for intraoperative guidance. Classical methods, su…
Image Retrieval with Intra-Sweep Representation Learning for Neck Ultrasound Scanning Guidance
Wanwen Chen, Adam Schmidt, Eitan Prisman +1
Purpose: Intraoperative ultrasound (US) can enhance real-time visualization in transoral robotic surgery. The surgeon creates a mental map with a pre-operative scan. Then, a surgic…
