XML Schema Representation of DICOM Structured Reporting.

چکیده
OBJECTIVE The Digital Imaging and Communications in Medicine (DICOM) Structured Reporting (SR) standard improves the expressiveness, precision, and comparability of documentation about diagnostic images and waveforms. It supports the interchange of clinical reports in which critical features shown by images and waveforms can be denoted unambiguously by the observer, indexed, and retrieved selectively by subsequent reviewers. It is essential to provide access to clinical reports across the health care enterprise by using technologies that facilitate information exchange and processing by computers as well as provide support for robust and semantically rich standards, such as DICOM. This is supported by the current trend in the healthcare industry towards the use of Extensible Markup Language (XML) technologies for storage and exchange of medical information. The objective of the work reported here is to develop XML Schema for representing DICOM SR as XML documents. DESIGN We briefly describe the document type definition (DTD) for XML and its limitations, followed by XML Schema (the intended replacement for DTD) and its features. A framework for generating XML Schema for representing DICOM SR in XML is presented next. MEASUREMENTS None applicable. RESULTS A schema instance based on an SR example in the DICOM specification was created and validated against the schema. The schema is being used extensively in producing reports on Philips Medical Systems ultrasound equipment. CONCLUSION With the framework described it is feasible to generate XML Schema using the existing DICOM SR specification. It can also be applied to generate XML Schemas for other DICOM information objects.

Research Paper: Generating XML Schemas for DICOM Structured Reporting Templates
In this paper, the authors describe a methodology to transform programmatically structured reporting (SR) templates defined by the Digital Imaging and Communications for Medicine (DICOM) standard into an XML schema representation. Such schemas can be used in the creation and validation of XML-encoded SR documents that use templates. Templates are a means to put additional constraints on an SR d...
متن کاملTowards An XML-Based Normalization for Healthcare Data Exchanges
Problem statement: Most of healthcare data exchanges are textual, poorly structured and often not accessible by clinical professionals. Otherwise, the variety of medical applications and medical standards makes difficult sharing and communicating healthcare data in a highly heterogeneous environment. Approach: XML and related standards (XML schema, XSL) provided an infrastructure that might cha...
متن کاملCytometryML, a markup language for analytical cytology
Cytometry Markup Language, CytometryML, is a proposed new analytical cytology data standard. CytometryML is a set of XML schemas for encoding both flow cytometry and digital microscopy text based data types. CytometryML schemas reference both DICOM (Digital Imaging and Communications in Medicine) codes and FCS keywords. These schemas provide representations for the keywords in FCS 3.0 and will ...
متن کاملUsage of XML technology in electronic health record for effective heterogeneous systems integration in healthcare
A virtual patient record is an ideal electronic health record (EHR) that is decentralised and contains heterogeneous clinical data. Extensible markup language (XML) is a web standard that has become the major driver towards heterogeneous systems integration for any industry solution. This work focuses on creating an XML schema that operates as an interface between different heterogeneous patien...

Content: In 1998, I proposed that the International Society for Advancement of Cytometry should replace their present Flow Cytometry Standard with an implementation in DICOM and work with the DICOM developers. After this suggestion was rejected, I suggested an XML implementation based upon DICOM to the International Society for Advancement of Cytometry Data Standards Task Force. Technology: XML...
