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

Embodiment 1

[0041] Example 1: Portable Fatty Liver Detection Device Based on Ultrasound

[0042] The system structure of the present embodiment device is as figure 1 As shown, it includes front-end ultrasonic transmitting and receiving device, processing chip and power supply. The front-end ultrasonic transmitting and receiving device includes a probe, a high-voltage pulse generator and an ultrasonic transmitting and receiving chip.

[0043] In this embodiment, the ultrasonic transmitting and receiving chip is the AFE5805 chip. The AFE5805 chip is used to control the transmission and reception of ultrasonic signals. The ultrasonic transmitting and receiving chip includes an ADC, and the number of the ADC is one.

[0044] The ultrasonic probe in this embodiment is a multi-element probe, which adopts frequency doubling setting, that is, the two emitted frequencies are integer multiples. The two frequencies can transmit at the same time, or one after the other with a time difference.

Embodiment 2

[0048] Embodiment 2: Data processing method of portable fatty liver detection device based on ultrasound

[0049] The device used in this embodiment is the ultrasound-based portable fatty liver detection device described in Embodiment 1, and this embodiment provides a processing method for the collected ultrasound data.

[0050] Specifically include the following steps:

[0051] (1) The ultrasonic probe emits cylindrical waves and collects ultrasonic echo data in a synthetic emission mode;

[0052] (2) Using aperture synthesis technology to reconstruct the data obtained from the transmitted cylindrical wave and the received echo to obtain beam data;

[0053] (3) Using parallel beam synthesis technology, changing the combination of the transmitting and / or receiving arrays of the ultrasonic probe, repeating steps (1) and (2), and superimposing the beam data obtained each time with the previous beam data, Obtain new beam data until all the array combinations for transmission an...

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...
