ブロックマッチングを用いた超音波心臓断層像における局所相対的オプティカルフロー推定

In order to detect ischemic and/or infarcted myocardium of a left ventricle, a motion of the cardiac muscle gives important information. Conventional method, such as center line method, may observe and measure the only overall motion of the myocardium using echocardiography.
In this article, we propose a new method to estimate using block matching. Then, applying this method to the echocardiograph, we estimate not only the overall motion but also local displacement of the myocardium on the echocardiogram.
