Abstract
The Finite Element method is a powerful numerical procedure for solving the physical problems. It has been proved to be a very useful tool in solving boundary value type problems in Biomechanics which are difficult to analyse by other closed form or numerical techniques due to their complexity and irregularity in shape & size. In this study, Finite Element method has been used to analyse the diastolic tissue elastic stiffness ("E"-value) of the Left Ventricle. A Computer Program has been developed to compare the "E"-values obtained by the Finite Element method and those obtained, by the closed form method. The concept of an index for normal Left Ventricle based on "E"-values has been discussed so that the ischemic tissue can be identified from the normal ones. The effect of Pin-Cushion distortion on the evaluation of tissue elasticity has also been studied; and it has been " found out that the angiographic images of Left Ventricle should be corrected (both for magnification & pin-cushion distortion) for accurate determination of regional "E"-values values.
