Improvement on Quality of Echocardiograms
Recently, since resolution of echo images have gradually improved more accurate tissue characterization utilizing echo images is anticipated. However, quantitative tissue characterization using echocardiograms is difficult in the existing circumstances, because significant deterioration is prevalent in echocardiograms. The primary cause for deterioration in image quality of echocardiograms is speckle noise components that appear on echo images. Since speckle noise is produced by random interference of ultrasonic pulse wave reflected from the body, it does not necessarily coincide with the minute structure of noise within the organic tissue construction itself. Therefore, it is necessary as a preprocess for tissue characterization to improve the quality of images by reducing speckle components without deteriorating the specular components that reflect the organic tissue structure.
