I'm developing a university course that has the goal of students building their own DICOMweb viewer in Python using GTK and https://dicomweb-client.readthedocs.io/en/latest/. Unfortunately the data stored in https://dicomcloud.azurewebsites.net is broken. All images referenced through the UID-links in studies and series are missing.
There is also
but they don't provide a standardized DICOMweb-interface but only individual downloads.
Note that the server
is buggy as discussed in this thread.
