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…
3D Ultrafast Shear Wave Absolute Vibro-Elastography using a Matrix Array Transducer
Hoda S. Hashemi, Shahed K. Mohammed, Qi Zeng +3
3D ultrasound imaging provides more spatial information compared to conventional 2D frames by considering the volumes of data. One of the main bottlenecks of 3D imaging is the long…
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…
Multifrequency 3D Elasticity Reconstruction withStructured Sparsity and ADMM
Shahed Mohammed, Mohammad Honarvar, Qi Zeng +4
We introduce a model-based iterative method to obtain shear modulus images of tissue using magnetic resonance elastography. The method jointly finds the displacement field that bes…
