My current research involves extraction, analysis, and visualization of large
3D Micro-CT images. The principal goals of incorporating algorithmic
improvements on accuracy and efficiency (in terms of storage and computation
complexity) are to help physicians explore the physiology and functions of
the vascular networks and identify abnormal branches.
In the past years, I evaluated the past work of related topics
and designed an automatic procedure of processing 3D Micro-CT images. The
procedure contains previous related research and my novel approach and
implementation of 3D segmentation and arterial network representation scheme.
My future research toward Ph.D. degree includes more analysis
details of the Micro-CT images and development of a visualization tool to
help explore/manipulate the extracted vascular networks. More validation of
the 3D image processing will also be surveyed before finishing the degree.
