Title: "Effectiveness metrics for medical visualization system"

Abstract

Volume visualization is an important research field with a wide range of
applications such as medical visualization. Rendering speed was one of
the major concerns in volume visualization, but with the rapid
development of graphics hardware and volume visualization techniques,
many volumetric datasets can now be rendered in real time on a PC
equipped with a commodity graphics board. However, the effectiveness
issues of volume visualization are not well investigated and addressed.
It is difficult for users to know how well they explored the data after
a visualization process, and it hinders the use of visualization tools
especially for non-expert users. In this thesis, we introduce several
effectiveness metrics for medical visualization systems in three levels
- voxel-level, surface-level and structure level. Given some useful
information in volumetric data users may be interested in, our metrics
can quantitatively measure how well users explored the data in a
visualization process. Feedback will be given instantly and intuitively
to users by effectiveness graphs, voxel images and voxel bar charts. The
metrics can be integrated into typical volume visualization systems and
can provide users with real time effectiveness evaluation to help them
achieve their goals.
