Called AE Title Not Recognised error in echoscu

问题

I was trying to test the connectivity of dcmqrscp. I have used the following command for starting dcmqrscp.

dcmqrscp --config C:\Dicom\config\dcmqrscp.cfg

Please find the below config file that I used.

NetworkTCPPort  = 11113
MaxPDUSize      = 16384
MaxAssociations = 16

HostTable BEGIN

acme1           = (ACME1, localhost, 1234) 
acme2           = (ACME2, localhost, 5678)
acmeCTcompany   = acme1, acme2

HostTable END

VendorTable BEGIN

"Acme CT Company"   = acmeCTcompany

VendorTable END

AETable BEGIN

ACME_STORE   C:\Dicom\echo   RW (100, 1024mb)   acmeCTcompany

AETable END

I've created C:\Dicom\echo as well before running the dcmqrscp command. The following echoscu command was used to test the connectivity of dcmqrscp: echoscu -d localhost 11113 -aec ACME_STORE -aet ACME1

But I am getting the following error:

One of my observation:In normal echoscu operations,the data dictionary is loaded correctly.But in the above logs of echoscu,we couldn't find any data dictionary load operations.

Could you please help me resolve the issue.

回答1:

I will extend my comment, as this might be helpful in the future. I think that the following scenario results from incorrect hosts configuration, unfortunately I cannot check this now.

When echoscu connects to dcmqrscp, the latter receives association with the following parameters: callingPresentationAddress, callingAPTitle, calledAPTitle. First parameter is just the unique host address of echoscu.

If both echoscu and dcmqrscp run in the same Windows machine, callingPresentationAddress is set to value of the hostname. The value can be obtained by ipconfig /all in the section Windows IP Configuration:

>ipconfig /all

Windows IP Configuration 
  Host Name . . . . . . : MY_PC
  Primary DNS Sufix . . :
  Node Type . . . . . . : Hybrid
  IP Routing Enabled. . : No
(...)

The same value should be set in dcmrscp's config file in HostTable section:

HostTable BEGIN
acme1           = (ACME1, MY_PC, 1234) 
(...)
HostTable END

回答2:

Did you also make sure that the directory C:\Dicom\echo is writable? Does it work if you change "acmeCTcompany" (last column in your "AE Table") to "ANY"? In any case, I would also start the dcmqrscp with -d (--debug) in order to see more details.
