DICOM @ OFFIS

Thank you very much for your answers! In our DICOMscope application, the GUI will not permit you to apply a GSPS to a "wrong" image (e.g. from a wrong series), so this case never happens. Are you sure? I was actually talking about the DicomScope behaviour. When I load an image from filesys...

Hi OFFIS team, I am not sure if these are DicomScope or general GSPS issues. I am currently validating my self-created GSPS objects with DicomScope and found some unclear behaviour which you hopefully could clarify: 1. I have a GSPS file containing a ReferencedSeriesSequence with a single item conta...

Thank's Michael,

I definitively have to update my code base to 3.5.4 since the DatasetIsComplete function does not exist in 3.5.3.

Best regards,

Hello OFFIS team, the default behaviour of wlscpfs.exe is to expand an empty sequence in a search mask. This behaviour is commented in the source code: According to the 2001 DICOM standard (part 4, section C.2.2.2.6), if a search mask contains a sequence attribute which contains no item or a single ...

but cannot send files from K-PACS to be stored at dcmqrscp enable the "Log DICOM Communication" option in K-PACS' "Job's" dialog and select "Debug" log mode. This will log the complete DICOM communication and will probably tell you why the association was aborted. Rega...

(0008,0060) CS [USA] # 4, 1 Modality ??? Most modalities either query for their own identifier (in your case "CT") or their own station name. "USA" will probably be ignored by your scanner. Another issue (at least with SIEMENS Syngo) is, that (0008,0015) SpecificCharacterSet is ...

Thank's for clarification!

it is just pointless since for such objects the "compressed" representation is actually the same as Explicit VR Little Endian.

yes, sure. I just was not sure if it would be neccessary for our DCMTK based server to decline compressed TS for non-image SOP.

Hi Offis team, in my search for an 8bit palette to 24bit RGB converter (due to the fact that E-Film even with V3.0 does not support 8bit palette color) I found, that dcmcjpeg.exe from V3.5.3 does this convertion prior to the compression (which of cause leeds to a very poor compression ration regardi...

Thank you very much!

I somehow missed the fact that createScaledImage actually creates a new object. Now everything works as expected.

Hi OFFIS team, I tried to implement an on-the-fly thumbnail creation into StoreSCP.exe (3.5.3) which works fine except for the fact, that this gives a memory leak. Since I am not very familiar with C++, could you give me a hint were the leak might be produced? I placed this code directyl after the s...

I think I messed something up...
I will try to track down the problem, but maybe I should simple take it as a hint to upgrade to 3.5.4

Thanks and Best Regards,
Andreas

Hi DCMTK team, I linked dcmnet against dcmjpeg in order to implement an on-the-fly decompression in storescp.exe After a day of racking my brain I managed to compile a working application. What I was struggling with is a doubling of MetaHeader tags after DataSet->chooseRepresentation. All the files ...

Hello Offis Team, I encountered as strange communication problem with an old GE ProSpeed scanner and the Offis StoreSCP (a slightly modified version based on 3.5.3 shipped with K-PACS). When sending from the scanner the StoreSCP receives the data without error messages but the pixel data seems to be...

Thank's for your explanation, Marco!

I will use version 3.5.4 from now on the solve the lossless compression VOI LUT issue.

dcmcjpeg version 3.5.3 for Windows. I could read in the manual files that option --rescale-identity is set by default. # This options prevents the creation of a modality transformation # other than an identity transformation (which is required for # many DICOM IODs). Window center/width settings enc...
