Project Title:

Virtual Anatomy and Dexterous Simulators for

Minimal Access Cardiothoracic and Neuro-endoscopic Surgeries

 

PI – Prof. Pheng Ann Heng

Abstract:

 

Building upon our recent advanced research development in virtual reality, visualization, imaging and biosensors research, together with our world-class medical expertise and our strong partnership in the Chinese Visible Human Project, this research team has the unique combined strength and adequate imaging resource to develop next generation highly interactive and realistic virtual environments for medical education and surgical training. The latest CVH male dataset is about 1143 GB in size. There are in total 18,200 cross-section digital images (4064x2704 pixel resolution, 48 bits color) at 0.1mm intervals; extremely fine anatomical details can be observed. We would like to explore new possibilities for using such ultra-high resolution data in multiple directions for medical research, education, surgical training and simulation.

 

In the project, our long-term key objectives include:

1.          Through original research, innovative application and intelligent integration of new advances in computing and engineering to develop state-of-the-art virtual anatomy and surgical simulators.

2.          To advance the frontier of medical visualization, biomedical computing and digital human research.

3.          To promote VR-based medical education and surgical training in China and the region.

 

The following major deliverables are expected in this proposed research:

1.          Highly interactive, multi-sensory virtual environments that support in-depth learning of virtual and functional anatomy, focusing on cardiac and neuro anatomy.

2.          Virtual reality based dexterous simulator for minimal access cardiothoracic surgery

3.          Virtual reality based dexterous simulator for neuro-endoscopic surgery
