A MESHED ATLAS VISUALIZATION TOOLKIT IN A JAVA-BASED CAD PLATFORM

Abstract

In this paper we have demonstrated a Meshed Atlas Visualization Toolkit (MAVT), an automatic mesh generator, which is a set of comprehensive libraries as well as a number of interactive tools in Java Platform. It covers a wide range of fundamental functions from image conversion and transformation, image segmentation and analysis, to geometric model generation and manipulation, all the way up to 3D visualization and interactive simulation. The toolkit successfully visualized a multi-structured 3D biomechanical human brain CAD model (3D meshed atlas) using the Cerefy Brain Atlas database. The scope of the tool has also been expanded to the collaborative CAD environment through a virtual design studio (VDS) that facilitates synchronous dynamic collaboration between geometrically dispersed users. The developed tool is expected to contribute in neurosurgical simulation and other clinical and web based application development. We have validated our model by geometric matching 2D cross sections and in-vitro indentation experiment on pig brain to compare tissue deformation with the result.
