Design And Realize The Upper Layer Software For The Digital Ultrasonic Equipment

In the present medical organization, the ultrasonic equipment has already become one of the capital equipment of medical diagnosis. Especially in recent years, with the rapid development of the computer, information and electronic technology, the ultrasonic diagnostic device changes with each day too. In order to keep up with the paces of development, entrusted by Ultrasonic Electronics Co., Ltd. of Wuhan, we developed the upper layer software for the digital ultrasonic equipment. First of all, make the brief introduction for ultrasonic development of technology, present ultrasonic kind and ultrasonic equipment principle, the feedback suggestion of combining the customer's demanding and users has proposed the principle and goal of the software design. Secondly introducing standard modeling language UML, utilizing UML carry the software on modeling, and divide it each functional block. Then the key technology in the development course to the software of the article has been discussed sequentially, including: The development of USB 2.0 interface drivers, provide the detailed development step; The compression of the ultrasonic image data, has analysed the necessity of the ultrasonic image compressed, and according to the characteristic of the ultrasonic image, compressed it by RLE method; Two kinds of ultrasonic image memory forms, storing the scheme long-range and distributedly of the ultrasonic image. Then, at the request of customer, have realized every anticipated function progressively under the environment of development of Delphi, make the whole software be realized, passing test, the operation that the software can be normal and steady on Windows operating platform. Finally, the article summarized some achievements and experience and looked forward to.
