Recent Projects

The objective of my research is to develop 3D reconstruction and real-time localization techniques for rigid/deformable environments to facilitate medical robots working in minimally invasive surgery. I have been working on two research projects for my Ph.D. research:

3D Acetabular Surface Reconstruction from 2D Pre-operative X-ray Images using SRVF Elastic Registration and Deformation Graph

Technical Details | Code and dataset will be released soon

This work proposes a novel framework that integrates square-root velocity function (SRVF)-based elastic shape registration technique with an embedded deformation (ED) graph approach to reconstruct the 3D articular surface of the acetabulum by fusing multiple views of 2D pre-operative pelvic X-ray images and a hemispherical surface model. Validations using both simulation and real patient datasets are performed to demonstrate the robustness and the potential clinical value of the proposed algorithm. The reconstruction result can assist surgeons in selecting the correct acetabular cup on the first attempt in primary THA, minimising the need for revision surgery.

3D Reconstruction of Colon Structures and Textures from Colonoscopic Videos

Developed Colonoscopy Simulator and Source Code | Technical Details

In this research project, I focused on developing SLAM-based frameworks to reconstruct the 3D maps of the deformable human colon from standard colonoscopy procedures, thus the unsurveyed regions (where precancerous polyps may reside) can be shown on the reconstructed colon maps and help colonoscopists to ensure more colonic surfaces are inspected and to reduce polyps missing rate. Due to the unavailability of complete colonoscopy datasets, I developed a realistic colonoscopy simulator that can simulate the colonoscopy procedures and generate complete colonoscopy datasets for validation of deformable reconstruction algorithms. The developed simulator was made publicly available to promote research in the field.

SLAM-TKA: Real-time Intra-operative Measurement of Proximal Tibial Resection Plane in Conventional Total Knee Arthroplasty

    

Technical Details | Code and dataset

In the second research project, novel SLAM algorithms were developed to improve bone resection accuracy in total knee arthroplasty (TKA). The proposed framework can precisely and real-timely pre-estimate the proximal tibial resection plane such that the evaluation processing does not need any external fiducials and does not interrupt the working flow of TKA.

Research

I'm interested in devleoping SLAM algorithms for image-guided robotics surgery (e.g. 3D human organ reconstruction, deformation recovery, surgical operation tools localization and navigation).
