ABSTRACT
The paper introduces the basic concept of metadata and the building process of metadata directory of TCM therapeutic principle and method information based on data meta-model,complementing a part of metadata directory of basic TCM method (therapeutic principle and method) of the Health Information Metadata Catalogue,summarizes problems found in the building process and advising on the further rationalization of the metadata directory.
ABSTRACT
The paper follows the preparation rules of health information data element standards,studies the catalog of statistical data element of Traditional Chinese Medicine (TCM) and the preparation contents,ideas and methods of value field code,prepares and forms Comprehensive Statistical Data Element Dictionary of Traditional Chinese Medicine and Classification and Coding for Value Domain of Comprehensive Statistical Data Element of Traditional Chinese Medicine,so as to provide reference standard and basis for the standardization and informatization in the statistical field of TCM.
ABSTRACT
Objective To realize the format conversion from DICOM images to common images with simple and convenient meth-ods. Methods Parsing the DICOM files adopting the object-oriented idea, the DICOM images were changed over on the basis of DCMTK toolkit. Results The VC++ project was built with the DICOM toolkit and the conversion of image formats was achieved. Conclusion This method conveniently achieves the conversion among kinds of image formats. The converted images are completely accord with the practicable standards;moreover, it's greatly convenient for the following processing and manipulations.
ABSTRACT
OBJECTIVES: Nowadays, as the amounts of biological data are rapidly increasing, bioinformatics has become one of the important research issues. The bioinformatics data sources are, however, distributed and heterogeneous, and therefore, often poorly integrated and difficult to use together. As many bioinformatics analyses need to make use of multiple information sources, the problem of integration of bioinformatics data sources has become an important one. The purpose of this paper is to present an integration system for bioinformatics data sources. METHODS: To solve this problem, we present an integration system for bioinformatics data sources using a global MDR, which provides users with efficiency and convenience as if they use one system. We deal with the extraction of data elements for bioinformatics MDRs by using ISO 11179 mandatory attributes. RESULTS: A global bioinformatics MDR schema for given MDRs and the results of query processing are presented. CONCLUSIONS: The proposed system and concepts in this paper may be a good solution for the integration of diverse bioinformatics data sources.

@#ObjectiveTo study a standardization to establish data element in medical data resource share.MethodsThe library of data element's structural glossary items was established frist, then whole data element was established by selecting structural glossary items, finally, the input of data element's character was executed.ResultsA standardization method to establish data element was desigened based on definition, structure and national standard of data element.ConclusionIt's a important work to share medical data resource that establish data element by standardization, and it must be followed correlative standard and select logical method.
ABSTRACT
The DICOM standard has greatly promoted the development of Medical Imaging and Communication. It′ s necessary to extract the pixels and convert the bytes to the format we need when process the DICOM files. JAVA open-source toolkit can be used to do this conversion with much convenience.
