Towards patient-specific optimization for mandibular reconstruction planning based on predicted bone-union propensity
Hamidreza Aftabi, John E. Lloyd, Amanda Ding +4
Mandibular reconstruction with vascularized bone grafts is complicated by donor-host nonunion, and virtual surgical planning produces a geometric plan rather than optimizing for bo…
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…
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…
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…
PIPsUS: Self-Supervised Point Tracking in Ultrasound
Wanwen Chen, Adam Schmidt, Eitan Prisman +1
Finding point-level correspondences is a fundamental problem in ultrasound (US), since it can enable US landmark tracking for intraoperative image guidance in different surgeries,…
Towards Transcervical Ultrasound Image Guidance for Transoral Robotic Surgery
Wanwen Chen, Megha Kalia, Qi Zeng +6
Purpose: Trans-oral robotic surgery (TORS) using the da Vinci surgical robot is a new minimally-invasive surgery method to treat oropharyngeal tumors, but it is a challenging opera…
Variational Shape Completion for Virtual Planning of Jaw Reconstructive Surgery
Amir H. Abdi, Mehran Pesteie, Eitan Prisman +2
The premorbid geometry of the mandible is of significant relevance in jaw reconstructive surgeries and occasionally unknown to the surgical team. In this paper, an optimization fra…
