Ultrasonic superposition denoising detection system based on digital compensation calibration

Abstract

The invention relates to an ultrasonic superposition denoising detection system based on digital compensation calibration. The ultrasonic superposition denoising detection system comprises an ultrasonic probe, a display screen and a host machine, wherein the ultrasonic probe is used for detecting tissues to be detected, the host machine is used for controlling the ultrasonic probe, the ultrasonic probe is provided with a detecting unit, the tissues to be detected comprise a static comparison tissue, a static standard image and a blank background, an image processor and a signal generator are arranged in the host machine, and the image processor comprises a comparison module, a superposition processing module, an analog-to-digital converter and a digital compensation module; the detecting unit comprises an odd bit unit and an even bit unit, the host machine controls the signal generator to successively send out odd and even bit signals for activating the odd bit unit to detect the tissues to be detected, and the signals are reflected to the even bit unit and the odd bit unit by the tissues to be detected to obtain even and odd bit detection signals; the obtained even detection signals and the obtained odd bit detection signals are subjected to superposition processing through the image processor, and the obtained image is displayed on the display screen.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an ultrasonic detection system. Background technique [0002] Ultrasonic detection is to detect moving organs and blood flow through ultrasonic probe based on the principle of Doppler effect, and display the detected signal on the display screen after image processing. At present, the ultrasonic probe is directly placed on the muscle tissue during detection. The disadvantages in the detection process are: when the probe is working, the surrounding environment noise affects the ultrasonic detection, resulting in noise on the image on the display screen, which affects image recognition; When a slight damage occurs, the operator cannot detect it from the image, so there will be a defect that the detection error is too large; and the adjacent elements on the ultrasonic probe crosstalk each other during detection, resulting in inaccurate detection results.
