Liver fatty degeneration ultrasonic measurement method and device based on image processing

The invention discloses a liver fatty degeneration ultrasonic measurement method based on image processing. The method comprises the following steps: preprocessing a group of RF (Radio Frequency) signals of an abdominal region including a liver region obtained by ultrasonic imaging, and converting the RF signals into grayscale images; processing the grayscale image to obtain a first liver region segmentation template; removing an interference signal region in the first liver region segmentation template to obtain a second liver region segmentation template; marking the grayscale image by using the second liver region segmentation template to obtain a region of interest; and in the region of interest, calculating an attenuation coefficient representing the fatty degeneration degree of the liver. Therefore, the attenuation coefficient can be calculated only for the sampling points in the liver and in the non-focus area, and more accurate liver fatty degeneration measurement is achieved. 本发明公开了一种基于图像处理的肝脏脂肪变性超声测
