The Design And Development On Extensible Integrated Visualization System Of Medical Data

The Integrated Visualization System of Medical Data is an information system to browse the clinical data in a certain navigate mode within a screen. With the rapid development of health care technologies, the types of the clinical data are grouping rapidly and with the increasingly complex of the clinical business, different clinical scenes have different needs of the data integrated view. Taking these observations into consideration, the Integrated Visualization System of Medical Data needs to have extensibility.Although the extensible of the Visualization System of Medical Data has been some studies, but the following problems are still included in the practical application:the coupling of the system and the underlying database is too high, system expansion is accompanied by a large number of database interface development; the system lack of good interactivity between the extension modules.To the problems mentioned above, this thesis does a research on Extensible Integrated Visualization System of Medical Data which includes:1) To the problem of high coupling between the system and the underlying database, this thesis has proposed a method of data binding based on openEHR two-level model approach. The system get data by openEHR Archetype Query Language (AQL). This method can avoid the frequent development of database interface.2) To the problem of lack of interactivity between the extension modules, a plug-in dynamic extension framework for the system is designed. The extension modules interact with each other by a flexible communicate interface.3) Based on above research, this thesis designed and developed a visualization system of medical data and the system has been used in clinic. The practice shows that the system can address the requirement of extensibility and expandability and the extension modules can achieve flexible interaction with each other. The system has been used in the outpatient department of a domestic top three hospital, it can meet the needs of different clinical scenarios in the outpatient department.
