Ultrasonic attenuation coefficient compensation system and liver fat detection system

Abstract

The invention relates to an ultrasonic attenuation coefficient compensation system and a liver fat detection system. An ultrasonic generator transmits pulse ultrasonic waves to the liver, an ultrasonic receiver receives echo signals of the ultrasonic waves, an ultrasonic attenuation coefficient obtaining module obtains a liver echo attenuation coefficient, a center frequency compensation module builds standard liver models in different thicknesses, an ultrasonic attenuation coefficient of the standard liver model in the corresponding thickness is measured, center frequencies of the standard liver models in different thicknesses are obtained through calculation, when the liver echo attenuation coefficient is measured, compensation is conducted at the center frequency of the model in the corresponding thickness so as to obtain a compensated ultrasonic attenuation coefficient, and quantitative detection is conducted on liver fat through the liver and kidney echo strength ratio H and the liver echo attenuation coefficient. According to the ultrasonic attenuation coefficient compensation system and the liver fat detection system, an image brightness level value is obtained through the liver ultrasonic echo signals, the liver echo attenuation coefficient is calculated more accurately, and then quantitative detection is conducted on liver fat through the liver and kidney echo strength contrast and the liver echo attenuation coefficient.

Description

technical field [0001] The invention relates to an ultrasonic attenuation coefficient compensation system and a liver fat detection system, in particular to an ultrasonic attenuation coefficient compensation system based on an ultrasonic center frequency and a liver fat detection system based on the relationship between attenuation and fat content. Background technique [0002] With the development of ultrasound technology and the development of ultrasound technology and medical technology, the requirement of non-invasive examination of liver lesions has increasingly become the focus of research. In the prior art, the qualitative estimation of liver fat is mostly carried out through ultrasound images, and there are also studies on the quantitative analysis of ultrasound attenuation coefficients. It is difficult to determine its compensation method. Therefore, in the liver fat quantitative detection system, there are not many effective methods. Contents of the invention ...
