Integrating the Healthcare Enterprise

  • Portable Data for Imaging - PDI

  • CDs that Work!


PDI – Actors and Transactions



CDROM Structure



CDROM Rules- Media Identification

  • The CD will have a human-readable identification on the outside of the physical medium. This should include:

    • Patient Name
    • Media Creation Date
    • Name of the Originating Institution
    • Indication of the type of content: “DICOM ONLY” or “DICOM PLUS WEB”


CDROM Rules- DICOM Content

  • Actors interchanging DICOM information will use the STD-GEN-CD Media Storage Application Profile.

  • Non-DICOM content will not be placed in the DICOM Directory.

  • All DICOM file names are limited to 8 characters (no extensions), uppercase letters, digits and underscore only.



CDROM Rules - Web Content

  • IHE_PDI web content corresponds exclusively to the DICOM content, although it need not represent the entire DICOM content.

  • Non-web content will not be placed in IHE_PDI directories.

  • Web content use of XHTML and JPEG formats is restricted to ensure interoperability.

  • All file names are restricted to the ISO 9660 8.3 file name. E.g. “support_for_my_app.dll” would need to be “SUPPORT.DLL” or some other 8.3 name.



CDROM Rules - Other Content

  • Other content will not be placed in DICOM or IHE_PDI directories, but may be placed in other locations on the CDROM.

  • Do not assume that an application on the media will automatically be launched. IHE recommends that media readers not automatically run software on the media.

  • All file names are restricted to the ISO 9660 8.3 file name. E.g. “support_for_my_app.dll” would need to be “SUPPORT.DLL” or some other 8.3 name.



All PDI reading actors

  • Shall indicate to the user when they find DICOM instances that are not supported by the reader.

  • It is recommended that viewers not automatically run software found on the media (for security reasons).



PDI Importer (Reader) Rules

  • Portable Media Importer is required to have facilities to accommodate updating patient information to use values for the receiving enterprise, e.g. update patient ID.

  • Portable Media Importer shall be grouped with at least one of the following actors:

      • Evidence Creator
      • Acquisition Modality
      • Image Manager/Image Archive
      • Report Creator
      • Report Manager
      • Report Repository


Common Issues - CD File Structure

  • Failure to write ISO 9660 Level 1 CDs.

    • Media cannot be written using the Joliet file system
    • Media cannot include Rock Ridge extensions


Example of Invalid IHE PDI File System

  • isoinfo -l -d -i /home/smm/mesa_v/PDI/vendor-iso-images/myCompany.ISO CD-ROM is in ISO 9660 format System id: Volume id: IHE Volume set id: Publisher id: Data preparer id: Application id: Copyright File id: Abstract File id: Bibliographic File id: Volume set size is: 1 Volume set seqence number is: 1 Logical block size is: 2048 Volume size is: 222206 Joliet with UCS level 3 found NO Rock Ridge present



Common Issues - CD File Naming Conventions

  • File naming conventions apply to all files on the CD including:

    • DICOM File Names
    • Non-DICOM File Names
    • DICOM Viewer Application Name
    • The name of DLLs present on the CD


Common Issue - DICOMDIR Requirements

  • DICOMDIR must be valid. Watch for

    • wrong VR for attributes
    • bad lengths in elements
    • bad offset calculations in DICOMDIR
  • All DICOM Images must use EVRLE encoding.

    • No Image Compression is permitted.


Common Issues - Format of readme.txt and index.htm

  • Carefully follow the guidelines of the Technical Framework with regards to the README.TXT and INDEX.HTM files.
