Thanks for your encouraging reply. I am a cardiac electrophysiologist and do, among other things, radiofrequency catheter ablation of bypass tracts and reentry circuits. You may already know about the field, but it involves using electrical signals through catheters to localize discrete areas in the heart. The only "visual" tool we have is fluoroscopy, which is, of course, 2 dimensional. It is a bit of a struggle to conceptualize 3 dimensionally where you are in the heart at a given time. Studying plastic models, pictures and cadaver hearts help, but I though it would be useful to use a 3-D image of the heart which can be rotated in any plane. One could then "place" catheters anywhere in the heart and view their orientation. The major obstacle, I think, is to graphically represent the complex relationships of the many structures inside the cardiac chambers. Any information that you might have would be greatly appreciated. -Frank
