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.
