Liver Parenchyma Ultrasound Anisotropic Texture Quantitative Measuring Instrument

Abstract

The invention relates to a liver parenchyma ultrasonic nondirectional texture quantitative measuring instrument and a liver parenchyma texture measuring method. The measuring instrument comprises an ultrasonic instrument for conducting ultrasonic scanning on the liver, an input system for conducting image conversion, a texture measuring system and an output system for outputting liver ultrasonic images and texture measuring results. The invention further relates to the liver parenchyma texture measuring method. According to the liver parenchyma ultrasonic nondirectional texture quantitative measuring instrument and the liver parenchyma texture measuring method, by the utilization of the characteristic that pixels at the edges of small dot-shaped structural units are repeated, the sizes and the average gradient of the small dot-shaped structural units are detected in a region of interest, and then the texture of a liver with liver cirrhosis, the texture of a fatty liver and the texture of a normal liver are distinguished. A clinician operates easily, detected data are qualitative and quantitative, great convenience is brought to clinical diagnosis, meanwhile, diseases are quantitatively visited in a follow-up mode through the measuring instrument, and reliable quantitative follow-up visit indexes are provided.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to the technical field of liver disease diagnosis, in particular to an ultrasonic anisotropic texture quantitative measuring instrument for liver parenchyma and a method for measuring liver parenchyma texture. Background technique [0002] Texture is commonly known as pattern, and ultrasound texture is the reflection of the structure of the viscera in the ultrasound image on the ultrasound image. Liver cirrhosis, fatty liver and other diseases involving changes in the texture of liver parenchyma are common clinical diseases and frequently-occurring diseases, which pose a great threat to the health of the people. There is a well-recognized fact in the field of ultrasound that the liver parenchyma texture of cirrhosis is thicker than that of normal liver parenchyma, and the texture of liver parenchyma of fatty liver is thinner than normal liver parenchyma, but there is no wa...

AI Technical Summary

Problems solved by technology

There is a well-recognized fact in the field of ultrasound that the liver parenchyma texture of cirrhosis is thicker than that of normal liver parenchyma, and the texture of liver parenchyma of fatty liver is thinner than normal liver parenchyma, but there is no way to measure how thick and thin it is, only relying on ultrasound The subjective judgment of the doctor, the judgment standard varies from person to person, and the difference is very large

Therefore, mild fatty liver and liver cirrhosis are often not accurately diagnosed clinically

[0003] On the other hand, the ultrasonic follow-up and clinical treatment of fatty liver and cirrhosis are also a big problem. The texture changes of these two diseases are not obvious during the treatment process, and it is difficult to judge the direction of change with the naked eye of an ultrasound doctor. and the degree of change
