Happy to report that we finally got a MRI Scanner installed (delayed by COVID) to interface with the a dev RIS. I’m using a modified version of the Python Script that I posted on GitHub repo. It actually almost works out-of-the box with some issue yet regarding the StudyDescription tag not getting populated from the MWL, but it looks like I can use the StudyID tag, and then vendor should be able to help with the rest.
The RIS creates an order in the RIS database and then sends a HL7 message to the python script via the REST API. That creates a .txt file template for the .wl file and then creates the .wl using dcmtk. So, bottom line is that the .wl file is put in the WorkLists folder so that the scanner can query it.
The whole setup is running in Docker.

Except for the issue with the StudyDescription things seem to be working. The .wl file actually has more info, but some of those tags are not being returned in the response. Can probably work that all out with the vendor.
I will tidy up the script and update after further testing.
