Design And Implementation Of Handheld Medical Ultrasonic System Software Based On Android

The research on handheld medical ultrasonic system is of great significancebecause of the development towards miniaturization and portable direction.Android system has been widely used in almost mobile terminal equipmentbecause of the openness of source and novelty of application. This paper appliesAndroid platform to handheld medical ultrasonic system, and the main subjectionis the design and implementation of software in ultrasonic system.The hardware platform of the handheld medical ultrasonic system isOmap3530mini board. In addition, the paper constructs the entire structure,builds the development environment and designs the development process ofsystem software. According to the demand analysis, we intuitively illustrate thefunctional requirement via case diagram and activity diagrams. This paperdivides the system into four function modules: front end parameter control andimage display, measurement, storage management and system settings.Meanwhile this paper designs the hierarchy structure of system software basedon MVC (model-view-controller), which can make code layered, reduceprogram coupling and improve the modularity.On the Android platform, the process of analyzing probe XML files is basedon SAX method, the function of probe switch and parameters downloadadjustment is realized using adapter model combining with handler newsmechanism and JNI technology respectively. And this paper successfullyachieves figure drawing via Simple Factory Pattern combined with SingletonPattern and realizes the medical records management function utilizing SQLitedatabase technology. Moreover, this paper designs and implements the imagestorage management functions, including the management of folders and files.Finally, the paper realize some basic functions in system settings module, forinstance, hospital name, date and screen saver, etcAfter analyzing the interface layout and window management mechanism, thispaper mainly uses the XML files to achieve the interface layout, and operates thesystem using the screen gestures, for example, long-time press to start menu, thesliding switching of the interface and manual drawing on the screen, etc. Overall,the design of software has made the system more suitable for the handheldoperation, simple and convenient.
