Modality Simulator

Hi All,

Does anyone know of any (preferably free) software which can replicate the basic functions of a modality (DMWL, Store, Q/R)? I’d like one for diagnosing issues (which worklist servers are down, etc.), testing and training of staff with integrations.




Hi Gareth,

Have you had a look at the DVTk Modality Emulator ( You’ll have to register to download the installer or you can download the source code from Github (GitHub - dvtk-org/DVTk: DICOM Validation Toolkit).

You could also look at ‘jdicom’ which also has a modality emulator (JDICOM).



Hi @gareth.james.

We’ve used a combination of products that we can configure ourselves to test connections etc.

  • PACSgear for eg importing medical illustration images and Print2Pacs which uses a DICOM modality work list DMWL
  • Efilm (from the original free version)
  • GE RA600 (originally the DICOM works product) which does DMWL,C-store and find and can create rules to autoforward and manipulate DICOM tags and identifiers etc.

We are implementing Sectra PACS but found there is still a need to have a local configurable workstation capable of DICOM testing and routing - and sites are retaining their RA600 for that purpose.

I’d be interested to hear too how other PACS managers are doing this?

Hi. We also use JDicom and DVTK to simulate modality’s for testing. Most of the time we only use it when their are issues after the first connection attempt.

• CharruaSoft - TESTSCU

this works well for simple DMWL/QR.
(Sorry for the bump, but its useful info!)
