About

Wen Pei Liu is a researcher whose work sits at the intersection of medical imaging, computer vision, and robotic surgery. His most notable contribution is a pioneering method for 2D–3D radiograph to cone-beam computed tomography (CBCT) registration, published in 2014. This technique enables precise alignment of intraoperative X-ray images with pre-operative CBCT scans, a critical capability for C-arm image-guided robotic surgery. By solving the challenging problem of registering sparse, low-quality 2D images to high-resolution 3D volumes, Liu's work directly enhances the accuracy and safety of minimally invasive procedures, allowing surgeons to navigate complex anatomy with greater confidence. While his most cited paper has accumulated 14 citations—a modest number that reflects the specialized nature of the field—its impact is significant within the surgical robotics community, where it has informed subsequent developments in real-time image fusion and intraoperative navigation. Liu's research sits at the nexus of algorithm design and clinical application, demonstrating how robust registration techniques can bridge the gap between pre-operative planning and intraoperative execution. His contributions are particularly valuable for researchers and engineers working on the next generation of autonomous or semi-autonomous surgical systems.
