Paper Abstract

Optical imaging of transmembrane potentials in cardiac tissue is a rapidly growing technique in cardiac electrophysiology. Current studies typically use a monocular imaging setup, thus limiting investigation to a restricted region of tissue. However, studies of large-scale wavefront dynamics, especially those during fibrillation and defibrillation, require visualization of the entire epicardial surface. We have developed a panoramic cardiac visualization system using mirrors which performs two tasks: (1) reconstruction of the surface geometry of the heart, and 2) representation of the panoramic fluorescence information as a texture mapping onto the geometry that was previously created. This system permits measurements of epicardial electrodynamics over a geometrically realistic representation of the actual heart being studied.
