Abstract
The regional changes of cardiac wall deformation
and the wall stress are important for
evaluation of the myocardial functions. However,
their application for clinical diagnosis has
been limited, because it is difficult to measure
these regional myocardial parameters in the
intact heart.
Meier et a1. (1980) and Walley et a1. (1982)
used the radiographic images of the implanted
radiopaque markers in the beating heart to
estimate the local twist and segmental shortening
of small epicardial segment.
After elimination of the effects of the timevarying
displacements of the overall cardiac
motion using kinematic approaches, the local
deformation was represented by the regional
rotation tensor and the muscle wall stretch
tensor. Also , the changes of wall thickness
could be computed from the stretch tensor
under the assumption of the isochoric deformation.
