Liver cirrhosis ultrasonic image liver envelope extraction method based on digital image processing technology

Abstract

The invention provides a liver cirrhosis ultrasonic image liver envelope extraction method based on a digital image processing technology, which is used for processing a liver superficial section image, and comprises the following steps: traversing the upper part of an ultrasonic image by using a sliding window algorithm to identify whether a liver ascites area exists in the ultrasonic image or not; performing gaussian blur processing, binarization processing and morphological closed operation processing sequentially on the ultrasonic image to obtain a binary ultrasonic image; searching the processed binary ultrasonic image based on a traversal algorithm, and searching a pixel point set corresponding to the liver envelope to form a prediction film of the liver envelope; and fusing the prediction membrane into the original ultrasonic image, and removing pixel points of the pseudo membrane from the prediction membrane by adopting a gray difference algorithm to obtain a real membrane of the liver envelope. According to the invention, the prediction membrane and the real membrane of the liver envelope can be obtained at the same time, and a guarantee is provided for subsequent morphological characteristic analysis.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a method for extracting a liver capsule from an ultrasound image of liver cirrhosis based on digital image processing technology. Background technique [0002] Liver cirrhosis, as a common chronic progressive disease, has serious harm to the human body. With the development of the disease, it can gradually lead to portal hypertension, end-stage liver disease, and even death. Therefore, for Early auxiliary diagnosis and treatment of liver cirrhosis is very important clinically. [0003] At present, the early diagnosis of liver cirrhosis using ultrasound images can be divided into two aspects, one is based on the analysis of the morphological characteristics of the liver capsule, and the other is based on the analysis of the texture characteristics of the liver parenchyma. Among them, how to quickly and accurately extract the liver envelope line is very important when analyzing the ...

AI Technical Summary

Problems solved by technology

The traditional liver capsule extraction method mainly relies on manual marking by medical workers, which is inefficient and more dependent on experience. Therefore, it cannot meet the current needs of clinical auxiliary diagnosis
