1. Proposed Profile: National Extensions on PDI for Germany

  • Proposal Editor: Christoph Dickmann
  • Date: N/A (Wiki keeps history)
  • Version: N/A (Wiki keeps history)
  • Domain: Radiology and other imaging domains

2. The Problem

The Portable Data for Imaging profile (PDI) defines a general way to exchange media (CD-ROM) with DICOM data, optionally web-viewable or other data.
Due to national regulations in Germany, the German Roentgen Ray Association (DRG) has initiated and sponsored work on how to use PDI so that German regulations are fulfilled. The result of this work is a non-IHE specification that partly extends, partly changes PDI requirements and recommendations.
Alignment work between the German authors and the IHE Radiology Technical Committee has already resulted in a number of Change Proposals to PDI. However, issues that could not be resolved in Change Proposals were considered candidates for a German National Extension of the IHE RAD Technical Framework's PDI profile.

The attached document is a draft for such a German PDI Extension to the RAD TF. It lists all the differences between the DRG specification and the PDI profile.


3. Key Use Case

The main use case is related to the German Röntgenverordnung and reliable digital image transfer by CD-ROM. In addition, there were numerous practical problems in the field where Radiologists were not able to view image data on CDs they were given by patients or colleagues.

In order to make digital image sharing as reliable as film-based image sharing, a number of requirements and recommendations are stated especially for Germany. These are listed in the proposed National Extension draft (see file below).

4. Standards & Systems

IHE RAD PDI.


5. Discussion

The proposal and open issues to be discussed can be found in this file: Media:IHE-RAD-TF-GER-PDI_20070828.doc. Solving these issues should be tackled together with IHE-D and the German authors.

The Brief Proposal "PDI large data sets - Brief Proposal" PDI large data sets - Brief Proposal covers on issue from the German PDI extension feature list: saving voluminous data on CD using the DVD compression mechanism. This requires collaboration with DICOM.

It should be checked if there are results from this work that can be generalized, i.e. are relevant to the PDI profile (international scope).
