dcmregistry2js

This project contains XSLT files to extract:

• the attribute data dictionaries from DICOM part 6 and part 7, and
• the UID registry from DICOM part 6 and to convert them to a JSON data dictionary format used by https://github.com/chafey/dicom2ion-js. (Alternatively an XML dictionary can be created.)

To use:

• Get a copy of the DICOM part 6 and part 7 XML files from http://www.dicomstandard.org/current
  • Part 6 contains
    • Chapter 6. Registry of DICOM Data Elements
    • Chapter 7. Registry of DICOM File Meta Elements
    • Chapter 8. Registry of DICOM Directory Structuring Elements
    • Chapter 9. Registry of DICOM Dynamic RTP Payload Elements
    • Chapter A. Registry of DICOM Unique Identifiers
  • Part 7 contains
    • Chapter E. Command Dictionary including E.1. Registry of DICOM Command Elements and E.2 Retired Command Fields
• Place the DICOM files part06.xml and part07.xml in the input directory.
• There are 4 xslt tasks configured in the project:
  • Generate ./dist/tagsRegistry.json
  • Generate ./dist/tagsRegistry.xml
  • Generate ./dist/uidRegistry.json
  • Generate ./dist/uidRegistry.xml Run the desired extraction task.
• Alternatively invoke the XSLT files (extractTags.xsl, extractUids.xsl) from your favourite tool or the commandline.
  • extractTags.xl uses the part06.xml file as the source, and takes the following parameters:
    • format=json,xml - specify the desired output format (optional; default: json)
    • +part07={path/to/part07.xml} - specify the part07.xml file. (required; the "+" indicates this is an xml document-node)
  • extractUids.xl uses the part06.xml file as the source, and takes the following parameters:
    • format=json,xml - specify the desired output format (optional; default: json)

To Do:

• Improve the JSON output. The current output is a little ugly, but is compliant and funcitonal. The conversion is a combination of customized xslt and of some generic XML-to-JSON xslt. It may be possible to use the json namespace to craft something that will emit as nicer JSON.

To modify the xslt files, the VS Code extension XSLT Interactive Debugger may be useful.
