Abstract
The invention relates to an ultrasonic probe background denoising detection system based on gain adjustment. The ultrasonic probe background denoising detection system comprises an ultrasonic probe, a display screen, a host machine, a static comparison tissue, a static standard image, a blank background and an image processor, wherein the host machine is used for controlling the ultrasonic probe, and the image processor is arranged on the host machine and comprises a comparison module, a superposition processing module and a programmable gain amplification adjuster; the ultrasonic probe obtains a static comparison image through detecting the static comparison tissue, obtains a background noise image through detecting the blank background and obtains a dynamic detection image through detecting a muscular tissue; the comparison module carries out comparison processing on the static comparison image and the static standard image, and transmits comparison information to the programmable gain amplification adjuster; the superposition processing module carries out superposition processing on the dynamic detection image and the background noise image, and a detection image is obtained after the processing by the programmable gain amplification adjuster. The ultrasonic probe background denoising detection system has the characteristics that the detection errors are few, the detection image is clear, and the recognition is easy.
Description
Technical field
The present invention relates to field of medical technology, relate in particular to ultrasonic wave detecting system.
Background technology
Ultrasound examination be by ultrasound probe based on Doppler effect principle, internal organs and the blood flow of motion are detected, and by the signal detecting through image processes and displays on display screen.When ultrasound probe detects at present, directly probe is placed in muscular tissue, the shortcoming existing in testing process is: during probe work, be subject to the impact of surrounding enviroment noise, cause the image on display screen to have noise, affect image recognition; When slight damage appears in probe, operator cannot discover from image, and it is excessive that it detects error.
Summary of the invention
The applicant is for the above-mentioned shortcoming of existing ultrasound probe detection system, study and improve, a kind of ultrasound probe background denoising detection system based on gain-adjusted is provided, and it has and detects accurately, is easy to identification probe quality and easy to operate feature.
The technical solution adopted in the present invention is as follows:
A kind of ultrasound probe background denoising detection system based on gain-adjusted, comprise ultrasound probe, display screen and for controlling the main frame of ultrasound probe, also comprise static comparison tissue, static criteria image, blank background and be installed on the image processor on main frame, described image processor comprises comparing module, overlap-add procedure module and programmable-gain amplifying regulator; Described ultrasound probe obtains static comparison chart picture, by detecting blank background, obtains background noise image and obtain detection of dynamic image by detecting muscular tissue by detecting described static comparison tissue, described comparing module is processed static comparison chart picture and static criteria image comparison information is passed to programmable-gain amplifying regulator by comparing, and described overlap-add procedure module is processed detection of dynamic image and background noise image overlay processed and obtained detected image by programmable-gain amplifying regulator.
Beneficial effect of the present invention is as follows:
The present invention is by detecting static comparison tissue, and one is convenient for identifying the quality of ultrasound probe, on the other hand for the calibration of ultrasound probe, reduces to detect error; By by detection of dynamic image and the denoising of background noise image overlay, in the detected image obtaining, without noise, be convenient to observe.
Accompanying drawing explanation
Fig. 1 is operation principle block diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
See Fig. 1, the present invention includes ultrasound probe 2, display screen 4 and for controlling the main frame 1 of ultrasound probe 2, also comprise static comparison tissue 5, static criteria image 8, blank background 6 and be installed on the image processor 3 on main frame 1, image processor 3 comprises comparing module 31, overlap-add procedure module 32 and programmable-gain amplifying regulator 33; Display screen 4 is connected with main frame 1, and ultrasound probe 2 feeds back to main frame 1 by the information of detection, and processes and obtain image and be shown on display screen 4 through image processor 3.
Ultrasound probe 2 obtains static comparison chart as 51, obtain background noise image 61 and obtain detection of dynamic image 71 by detecting muscular tissue 7 by detecting blank background 6 by detecting static comparison tissue 5, comparing module 31 by static comparison chart as 51 with static criteria image 8 by comparing processing, the comparison information that obtains is on the one hand for identifying the quality of ultrasound probe 2: only have when static comparison chart as 51 and static criteria image 8 between difference within the specific limits time, ultrasound probe 2 could continue to use, otherwise needs to change; Pass on the other hand programmable-gain amplifying regulator 33: programmable-gain amplifying regulator 33 is adjusted image according to comparison signal, calibration ultrasound probe 2 makes its static comparison chart obtaining overlap with static criteria image 8 as 51, to reduce to detect error.
Overlap-add procedure module 32 is by detection of dynamic image 71 and background noise image 61 overlap-add procedure, and soon the noise in detection of dynamic image 71 passes to 33 processing of programmable-gain amplifying regulator and obtains detected image 9 after removing, and detected image 9 is shown on display screen 4; Due in detected image 9 without noise, it is clean, clear, handled easily personnel observe.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and without prejudice to spirit of the present invention in the situation that, the present invention can do any type of modification.
