DICOM @ OFFIS

Hello, I am reading lots of old posts about image compression and stumbled upon this one. Is the info in the link (documentation) still valid? I'm thinking of this piece: . . . // since the UIDs in the data set may have changed delete metaInfo->remove(DCM_MediaStorageSOPClassUID); delete metaInfo->r...

Hello again! Now I have some thoughts/questions about compression as a means of speeding up image transfer. We need to issue 448 C-STORE requests with CT IOD images (448 cols X 448 rows X 16 bits) to a dicom server over a 100 MBit/s LAN. It takes 17 s in practice for this transfer to complete, i.e. ...

I'll try to read the documentation better next time
I guess we could easily add another constructor that takes a reference to the dataset as input and avoids the copying.
Thus saving some time.

Now it works! The first problem was that our application saved pixel data as an DcmOtherByteOtherWord object. This have worked fine for a long time, but was no good for storing compressed data. When I switched to DcmPixelData object (also for non compressed data) it worked better. Problem nr two was...

Hello, We have a piece of code based on dcmtk that creates a dicom file using EXS_LittleEndianExplicit transfer syntax. This works fine. Now I am trying to add storage of compressed transfer syntax. I have registered a number of codecs. Problem is in DcmDataset::chooseRepresentation() After the sear...

Thank you, this fixed the problem.
I downloaded scu.h and scu.cc via the git link and rebuilt dcmtk-3.6.0 with them.
Then both 1) and 2) calls of sendSTORERequest works.

Hello, We have a problem when calling DcmSCU::sendSTORERequest without dicomFile but with DcmDataset. Our application is built on DCMTK 3.6.0 and it tries to send a DICOM image to STORESCP.EXE (also DCMTK 3.6.0) acting a server. We have followed the sample code available on Offis site. Call number 1...

HI, be sure you link all the DCMTK libraries you need, and link them in the correct order. For example, take the order from storescp linker directives found in the corresponding CMakeLists.txt: dcmnet dcmdata oflog ofstd. Michael Thank you! I was not aware that the order of libraries is important. ...

Thanks for all these hints! My problem right is actually quite mundane - I get a lot of "undefined references" errors when building. There is probably some difference with the DCMTK make files and the ones (Qt) we use in our project. Once I have that figured out everything should run smoot...

Hello, We want to use the Offis DMCTK toolkit for adding DICOM functionality to the medtech product we currently develop. The functionality we need is: - Dicom ping (C-ECHO) - DMWL query (C-FIND) - Send Secondary Capture Image (app screen dump) (C-STORE) So far we have successfully downloaded DCMTK,...
