Problems solved by technology

In order to obtain a higher signal-to-noise ratio of the far-field signal, it is necessary to increase the emission voltage, but the increase in the emission voltage will inevitably lead to saturation of the near-field signal when the gain is fixed.

Abstract

The invention provides fat content measurement system and method. The fat content measurement system comprises an ultrasonic measurement instrument and a user terminal; the ultrasonic measurement instrument is composed of a control device, an ultrasonic probe and a treatment device; and the user terminal is composed of a synthesis module and a calculation module. When the fat content measurement system is used for carrying out measurement, at least two ultrasonic echoes acquired by carrying out ultrasonic emission, receiving and treatment on a same measured object by adopting two-stage emitting voltages respectively are synthesized to obtain a synthesized ultrasonic echo, and the thickness and the content of fat of the measured object are calculated according to the synthesized ultrasonic echo. According to the fat content measurement system and method, under the conditions without adding a circuit and with cost conservation, the signal-to-noise ratio of a remote field signal is increased, a near field signal is unsaturated, and thus the measurement accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic application, in particular to a fat content measurement system and method. Background technique [0002] In traditional ultrasonic measuring instruments, in order to compensate for the attenuation of the ultrasonic echo signal as the depth increases, the time gain compensation (TGC) circuit is generally used to amplify the echo signal. This circuit is complex and expensive, and is not suitable for fat content. In low-cost, small ultrasonic instruments such as measuring instruments. Another method uses fixed gain, and digital gain is used for gain compensation in the back-end digital processing. Although this method saves the time gain compensation (TGC) circuit and reduces the cost, it will bring corresponding problems. Ultrasonic energy will attenuate with depth when it is transmitted in the human body, and the attenuation coefficient is generally 0.81dB / cm*MHz. If the ultrasonic transmission...
