Hi, there is no copy constructor which permits not to copy pixel data; also note that there may be other elements besides pixel data (like overlays, LUT data, ...) which may be larger than "normal" elements. What you can do before performing the copy: Remove the pixel data (but not delete ...

Hi,

Often the server is configured to accept only known AE titles, i.e. if you want to use a specific Called AE Title (and Calling AE Title) when connecting with your client, it might be necessary to pre-configure it's AE titles at the server.

Best regards,
Michael

In the A-ASSOCIATE-RQ PDU you must negotiate which SOP Classes you want to use. So be sure you negotiate the FINDStudyRootQueryRetrieveInformationModel there in order to be able to send a C-FIND-RQ later on. What I don't understand: You want to do C-FIND on Study Root, but: - something is written ab...

Hi, if you want to more C++ approach for implementing a DICOM (C-FIND) client, you may have a look at the new class DcmSCU, in dcmnet/libsrc/scu.cc which is part of the current snapshot. You can derive your own class from that SCU, use function like setAETitle and so on and also use API functions to...

Hi Per, indeed we have a list of known issues , though it is not very up-to-date regarding the snapshot (e. g. the current problem in OFString). We could/should extend that to the snapshot versions. Right, we don't have our version control logs publicly available, but any change to DCMTK is listed i...

Dear liyongyi, Right, DCMTK does not have any support for hanging protocols. The general mechanism is described in part 4 of the DICOM standard. Also, the original Supplement 60 which introduced Hanging Protocols to the standard may be worth reading (download linked at David Clunie's site ) Best reg...

It just seems that you accept the connect, query the database based on the query keys sent by Osirix and then you do nothing, ie. you don't send C-FIND-Response messages as you should do.

Hi Adrien, there is a very "sophisticated" way of deleting ... :wink: delete the DICOM file, then delete the index file and rebuild it with dcmqridx. There is no other way of removing a specific file. With movescu it's not possible because there is no DICOM command to delete files from a d...

Sorry, I have no special idea. The only thing is that, as far as I know, you must reserve the memory for the filename creation yourself and maybe it's too short. Try initializing the tempfile variable with "char tempfile[50]" or something before using it in mktemp.

Hi, the problem usually not lies in the DICOM storage protocol which should scale with the size of the transferred image. The only things I can think of is that the SR file is validated at the receiver (and maybe also at the sender) before an acknowledge is sent. Another issue is that maybe the Stru...

If you have created it indeed, it's the server's fault.
If you haven't created it, it's your fault.

Thats it :)

Hi,

how much memory is reserverd for the tempfile variable? What does it contain after the mktemp call?

Hi, it just seems that you abort the association and you do not send any responses. I would suggest going through it with a debugger. Also, (especially for debugging) I would suggest starting your tool in single process mode for testing. I don't expect that this is a DNS problem; your tool receives ...

Hi, which operating system does the resulting program run on? As we have heard, mktemp is making problems under Vista (maybe also Windows 7) because there mktemp is usually returning a filename in the root directory which then cannot be written (no rights) from the process. Maybe also the working di...
