Hi all!

I have a situation where I am trying to query and retrieve dicom data from a Dicom server, but the server does not send any data to the specified AE-title. I can do queries with C-FIND, but when I do MOVE, nothing comes to my listening process. Unfortunately, I do not have access to any server side logs for that server, so I have to interpret the ClearCanvas log on my side to get an idea of what is going on.

Here's the log output for sending the move request:

2010-07-15 09:38:34,809 [10] INFO  - Starting to listen with AE WORK5 on port 0.0.0.0:104

But in stead of getting any data, I get a series of responses like this:

Could anybody tell me what this last response means? Could it be that the server is trying to send to the wrong AE-title or that something is blocking on the network?

 

 

Does the server have your move destination AE title, WORK5, configured properly?

Thank you for the reply!

It could be that the server has not been configured correctly with my AE title and hostname/port. I will find this out later this week.
 

My main problem is that I do not really understand the message that I get from the server. I do not get data, and this pattern keeps repeating in the log:

What is it that this log message actually tells me?

The status in the log, 65280, can be converted to hex FF00, which means pending. Basically, while the remote system is processing the request, it should continue sending Pending response messages until the operation is complete. As it transfers images, the Suboperations counts should be adjusted as images are transferred. The odd thing is that the Number of Remaining Sub Operations is set to 0. In any case, this should be described in Part 4 of the DICOM standard in the Query/Retrieve section.
