Project Experiences
Title: 2014.06 ~ present, High-Precision Robotic-Assisted Targeting for Liver Biopsy and Ablation: A Feasibility Study (ASTAR JCO Project Grant), SBIC, ASTAR, Singapore.
Description: In this project, we propose a preliminary high-precision targeting solution framework to endeavor to conquer challenges and difficulties during existing manual needle-based liver interventions. This framework contains three key components: fast and robust tracking technique to detect the liver respiratory motion (especially tumors), needle-liver interaction biomechanics model to calculate the liver deformation under needle insertion, and robotic device to steer the needle stably and precisely. The former two components will be developed and integrated into our robotic system to establish a high-precision robotic-assisted targeting solution framework. Main goal of this project is to identify key technologies for accurate targeting and their feasibility in clinical settings, not build a practical and complete solution to needle targeting.
