It delivers information about the geometry, motion and position of the heart. Trials to perform tissue characterisation based on ultrasonic images of the myocardium have not led to reliable results, yet. It has been developed in a cooperation with the Department of Cardiology of the Klinikum Neuruppin. In contrary to the image based techniques it works directly on the ultrasound rf-echos. The digital rf-data is finally stored on a hard disk.
Further processing is done off-line.
The rf-data is segmented in different areas representing myocardium, pericardium and blood. Features are extracted from the areas containing myocardium. The last step classifies these features.
