Based On Virtual Instrument Of Ultrasound Image Processing System

Ultrasound diagnosis is one of the most important methords of modern medicine diagnosis. The B ultrasonic diagnostic equipment that takes the supersonic phantom diagnostic equipment the predominant type uses widely. Along with material civilization development and people healthcare request enhancement, the people had a higher request to ultrasound diagnosis's accuracy. But in current diagnosis process, The picture quality is a big influence to doctor's judgment. Therefore, the picture quality becomes the important target of measuring ultrasound diagnosis instrument. Based on this, this article has conducted the research to the B supersonic diagnostic equipment's imagery processing system.The supersonic imagery processing system is mainly composed of two parts in this article:the image gathering and the image processing. The system uses the virtual instruments development platform to establish, the NI PCI-1411 image gathering card gathering the B ultrasonic diagnosis equipment images, and upload to the computer. Then the system will use the LabVIEW software and necessary NI IMAQ image processing toolkit, to carry on image processing and analysis at the obtained image, include pretreatment, edge detection, false colored processing, measuring of the target objects, etc.. Finally, the system will store the processing images and datas.Through repeated demonstration and experiments, in the virtual instrument development platform to design a simple, attractive interface of the PC testing system for B ultrasonic image processing, and realize the functions of image acquisition, processing, analysis and data storage. The system operation run stably and have lots of advantages such as:a short development cycle, fast track, use simply, beautiful interface, etc..The system would satisfy needs of clinical diagnosis.
