- Visualization of Bioelectric Phenomena
-
-
- Biomedical investigators are currently able to acquire and analyze
- physiological and anatomic data from three dimensional structures in
- the body. Often, multiple kinds of data can be recorded
- simultaneously. The usefulness of this information, either for
- exploratory viewing or for presentation to others, is limited by the
- lack of techniques to display it in intuitive, accessible formats.
- Unfortunately, the complexity of scientific visualization techniques
- and the inflexibility of commercial packages deter investigators from
- using sophisticated visualization methods that could provide them added
- insight into the mechanisms of the phenomena under study. Also, the
- sheer volume of such data is a problem. High-performance computing
- resources are often required for storage and processing, in addition
- to visualization.
-
- This talk will describe a novel, language-based interface that allows
- scientists with basic programming skills to classify and render
- multivariate volumetric data with a modest investment in software
- training. The interface facilitates data exploration by enabling
- experimentation with various algorithms to compute opacity and color
- from volumetric data. The value of the system is demonstrated using
- data from cardiac mapping studies, in which multiple electrodes are
- placed in and on the heart to measure the cardiac electrical activity
- intrinsic to the heart and its response to external stimulation.
