| Outline of Final Research Achievements |
As the first step toward 3D echo-guided surgery in the beating heart, optimal surface property for echo visualization was studied. By using 11 materials, clarity of echo image, especially at a large incident angle, was compared with the microscopic shape of the surface of each materials.
A material with irregular surface (rough surface), not a flat and smooth surface, proved to be better visualized by echo irrespective to the incident angle as well as associated with less aftifact (smaller area of side lobes).
