Portable fatty liver detection device based on ultrasound and data processing method thereof

Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to a portable fatty liver detection device based on ultrasound and a data processing method thereof. Aiming at the difficulty in miniaturization and portability of an ultrasonic-based fatty liver detection device in the prior art, the invention provides a data processing method of the portable fatty liver detection device based on ultrasound, and the method comprises the following steps: enabling an ultrasonic probe to emit ultrasonic waves with at least two frequencies and receive ultrasonic echo data; performing beam forming on the ultrasonic echo data to obtain ultrasonic RF data; and finally, according to an instruction of a user, outputting the ultrasonic RF data, or performing post-processing on the ultrasonic RF data in the portable fatty liver detection device. The invention further provides a portable fatty liver detection device which is simple in structure, low in power and small in size. Under the condition that the requirement for the chip structure is extremely low, portable equipment can detect the fatty liver by obtaining an ultrasonic attenuation coefficient or an elastic imaging result and the like.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an ultrasound-based portable fatty liver detection device and a data processing method thereof. Background technique [0002] Fatty liver refers to a disease in which more than 5% to 6% of normal liver tissue is replaced with fat. In this disease, the accumulation of fat leads to inflammation, cell death and scarring, also known as non-alcoholic steatohepatitis. If left untreated, steatohepatitis can lead to liver fibrosis, which can lead to reduced blood flow throughout the liver and the formation of scar tissue. Further, hepatic fibrosis may lead to cirrhosis, liver failure and liver cancer. From a global perspective, about 1 / 4 of the population suffers from non-alcoholic fatty liver disease, with slight differences in different countries and differences in different populations. The prevalence of fatty liver in my country is slightly higher than the gl...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that one of the main factors restricting the miniaturization and portability of the fatty liver ultrasonic detection device in the prior art is that the processing process of the ultrasonic signal is relatively complicated, which leads to relatively complicated components such as the chipset of the device, so the power supply of the device is relatively complicated. , heat dissipation and occupied space have adverse effects
