The term "computational biomechanics" describes the approach taken in a 3-year project promoted by the National Cardiovascular Center of Japan to integrate fluid and solid mechanics in studies of the heart and vascular system. The goal was to create a new, comprehensive methodology in cardiovascular research, including both radiological and electrophysiological studies to achieve the most comprehensive view. This book compiles reports of the work conducted by leading researchers in biomechanics using a full array of cutting-edge technology - from the supercomputer in the National Cardiovascular Center to individual PCs. The book stresses application rather than development of theory, thus appealing to a wide audience ranging from researchers without extensive backgrounds in computation, to graduate students and clinical practitioners. Enhanced with color illustrations, the book is a valuable resource in biomedical engineering.
