Abstract：To propose a enhancement algorithm of ultrasonic image for improving the capability of grading diagnosis in fatty liver.The algorithm which combines the piecewise linear transformation of gray level was proposed and the local contrast ratio enhancement was improved, by analysing the characteristics of ultrasonic image in normal liver and fatty liver with different degree.The features of fatty liver in ultrasonic image were highlighted with the piecewise linear transformation of gray level.And the details of image were enhanced with the improved local contrast ratio enhancement processing while improving the quality of ultrasonic image.The ultrasonic images of normal liver, mild fatty liver, moderate fatty liver and severe fatty liver were processed with the enhancement algorithm.By comparing the original images, it could be found that the enhanced images had better features of fatty liver and better image details, and the differences in images of fatty liver with different degree were more obvious.It showed that the enhanced images had better information for diagnosing fatty liver.The enhancement algorithm proposed can improve the capability of grading diagnosis in fatty liver, has some references to practical application.
