No, I don’t think there’s anything more written up - but it uses pretty standard dicom networking terminology and concepts so if you need background there are resources linked at the bottom of the page. The topic can get pretty deep quickly. Often the hard part is finding out the right ports and AETITLE info for your local system. That’s why you may want to use the dcmtk command line utilities I pointed to in the CTK test program comments to debug and then enter the info to Slicer once you know they work.
Also the folks at Medical Connections are nice enough to run a public PACS for testing and Slicer comes pre-configured to query/retrieve from that. So you can see if you can just copy that over to your setup.
Basic steps:
Enable the medical connections server, pick a search option and click Query:
Select a patient and click Retrieve, data is put in Slicer dicom database:
Load result:
