Re: Retrieval of pixel data of Segmentation storage

Hi Michael, Thanks for your answer. Altough your fix seems totaly related to my issue here, it nevertheless turns out the problem was coming from my side. I used the method DcmDataset::findAndGetUint8Array() to access the frame pixels bits array, whereas the recommended way to access pixels array fr...

Hi, Basically I'm working on a DICOM import feature for Segmenation storage, in a commercial application for scientific data visualization and analysis, and I'm ecountering an issue to have this feature work consistently. My problem is: when I retrieve the pixel data (7FE0,0010) from a DICOM segment...

Re: Reasons for hang on ASC_requestAssociation() ?

The Tcp port I used between the sender and the receiver was also used elsewhere.
I did change that. Now everything works just fine.
Problem solved.

Re: Reasons for hang on ASC_requestAssociation() ?

I pushed my investigation a bit further : I compiled dcmtk in debug with pdb files and followed execution into it to see where the code hangs. Actually it hangs on a call to recv() function of the Winsock API , in the DcmTCPConnection::read() method. And, again, when the receiver is launched as a SY...

Re: Reasons for hang on ASC_requestAssociation() ?

@Michael Onken: We do not use the storescp application but a code of our own inspired from the storescp example (file dcmtk/dcmnet/apps/storescp.cc ) @Jan Schlamelcher: I meant this section indeed, but also this one: On Windows, QProcess uses the Win32 API function CreateProcess to start child proce...

Re: Reasons for hang on ASC_requestAssociation() ?

Actually I took a look a bit closer of the primitives I use to create the receiver and I found some interesting info. The OS our software solution works on is Windows: - Without my changes the receiver is created with the ::OpenService() primitve that creates a Windows Service (in this case User Nam...

Reasons for hang on ASC_requestAssociation() ?

Hi all, I am experiencing a difficult issue that I can't really explain. I work on a software solution (several executables) and two of them exchange DICOM data through DCMTK. The emiter is a standalone executable and the receiver is a SYSTEM process launched by one daemon of our own. The emission /...

Re: How to insert a Sequence with undefined length ?

Thank you Good Sir,
That is exactly what I was looking for ! :D

Just out of curiosity, and in case of a possible further need, how do we do a such mixed data set ?

How to insert a Sequence with undefined length ?

Hi, I have been struggling to insert a sequence, but with an undefined length, into a data set. The insertion of the sequence, as well as the insertion of all direct and indirect childs, is done correctly though. But when I load the DICOM filed generated with Sante DICOM Hexadecimal Viewer I get thi...
