"Computer-Aided Heart Motion Analysis"
Assessment of cardiac function and early detection of abnormality play an essential role in the diagnosis, treatment, and control of several heart diseases. Visual assessment of cardiac function may result in higher inter- and intra-observer variability. Alternatively, automating abnormality scoring and producing clinically relevant quantitative measurements are desirable to facilitate the disease diagnosis. Due to the similarity between the statistical information associated with normal and abnormal heart motions, the heart motion abnormality detection is acknowledged as a difficult problem, which has recently bestirred a significant research attention. Our study investigates several fundamental problems related to cardiac images acquired in regular clinical routine. First, this study investigates automating the analysis of global cardiac function, and proposes effective measures to process the information from the data. Then, it addresses the problem of uncertainties associated with cardiac motion and proposes solutions based on a more complex motion models. Finally, a solution to the regional myocardial abnormality analysis is developed in accordance with the clinical standard issued by the American Heart Association.
