Abstract
This thesis addresses the problem of providing a quantitative analysis of left ventricular function through the use of two-dimensional echocardiography. A digitized image of the left ventricle is obtained from a clinical ultrasonograph at end diastole and end systole. Several image enhancement methods are applied to these images to enhance the left ventricular endocardial border. A quantitative analysis of left ventricular volume, expressed as ejection fraction is obtained from the enhanced. images. a significant correlation is found between the ejection fraction determination from the enhanced images and the ejection fraction determination made by an echocardiographer from the original unenhanced images. A technique for the characterization of tissue based on its echogenic property is also presented.
