Embodiment Construction

[0017] The embodiments of the present invention will be described in more detail and complete below in conjunction with the accompanying drawings. The specific embodiments described here are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention.

[0018] exist figure 1 , shows the signal processing flow chart of obtaining the fat attenuation coefficient from the ultrasonic echo signal. The lower computer collects the ultrasonic echo signal and uploads it to the upper computer. First, the original signal is de-gained, and then the signal is band-pass filtered to remove interference noise. , use the Hilbert transform to perform envelope detection on the filtered signal, then logarithmically transform the detected signal, and then perform smoothing filtering and down-sampling after obtaining the data, perform linear fitting on all continuous points to find the slope of the line, and finally find The attenuation coeffi...

Abstract

The invention relates to a fatty liver detecting system based on an ultrasonic attenuation coefficient, and belongs to the technical field of signal processing and liver attenuation coefficients. Thefat contents of livers of patients with different degrees of fatty liver are measured, a lower computer acquires an ultrasonic echo signal and uploads the ultrasonic echo signal to an upper computer,gain of an original signal is removed at first, then the signal is subjected to band-pass filtering to remove interference noises, a filter signal is subjected to envelope detection by hilbert transform, then the detected signal is subjected to logarithm transformation, after data are obtained, the data are subjected to smoothing filtering and down-sampling, all continuous points are subjected tolinear fitting to solve straight slope, finally, an attenuation coefficient which corresponds to the data is solved, in the calculating process, the fat content in the liver is measured by calculatingthe attenuation degree of the ultrasonic echo signal in human body liver fat, and the fatty liver detecting system based on the ultrasonic attenuation coefficient can be used for measuring the attenuation coefficient of liver tissues and detecting the degree of fatty liver.

Description

technical field [0001] The invention relates to a fatty liver detection system based on an ultrasonic attenuation coefficient, and specifically relates to a system for detecting the fat attenuation coefficient by an ultrasonic method to judge the degree of liver fat. Background technique [0002] Fatty liver refers to the lesion of excessive fat accumulation in liver cells caused by various reasons. It is a common pathological change of the liver, rather than an independent disease. Fatty liver disease is seriously threatening the health of the Chinese people, becoming the second largest liver disease after viral hepatitis, the incidence rate is constantly increasing, and the age of onset is getting younger. Normal human liver tissue contains a small amount of fat, such as triglycerides, phospholipids, glycolipids, and cholesterol, and its weight is about 3% to 5% of the liver weight. If too much fat accumulates in the liver, it exceeds 5% of the liver weight. Or when more ...
