@lassoan no, I am not in constant contact with Eigen. I do know someone at Eigen, who may have more insight on this, and I will forward the thread. However, based on my experience, I don’t recall when vendors were eager to address this kind of issues raised by researchers. For anything to change, those should be raised by paying customers. I am afraid the reality is that 1) lack of following DICOM standard or conventions as in this example often does not cause troubles for paying users (clinical users); 2) attempts to follow the standard precisely may cause troubles for paying users, because the downstream systems working with the data may not be able to deal with the proper implementation of the standard.
I agree we all should keep raising those issues with the vendors. But most importantly, I hope that paying customers do this more often.
