Re: Sending an IOCM DICOM object

Hi, first of all: your understanding is correct. It should be possible to create such a file using dump2dcm. If you can get hands on a Key Object Selection (KOS) file then you could use dcmdump and use that as a starting point. Googling I can see that here at the Weasis page there is a such a KOS fi...

Re: move data from one pacs to another

Hi,

you would need some extra scripting, probably a combination of findscu and movescu would do.

Best,

Re: dump2dcm

Hi Justin, To.your second call, append the desired name of the output file: dump2dcm "C:\Program Files\dcmtk-3.6.7-win64-dynamic\OFFIS\wklist1.dump" > "C:\Program Files\dcmtk-3.6.7-win64-dynamic\1.wl" Also, make sure you have permissions to create files in C:\Program Files\dcmtk-...

Re: dump2dcm

Hi Justin,

Just sounds as if the working directory you are in is not writable maybe?

Otherwise share your full commandline call.

Best,

Re: How to override incorrectly labeled VR values

Hi Spencer, it should not matter if the attribute is stored with data type UN in the file as long DCMTK knows it and fix the VR by looking it up in the dictionary when loading it into memory. Maybe something with the dictionary is wrong, or you haven't loaded one. Let's try to find out what happens....

Hi,

you are right, this doesn't look good. I created an issue on the issue tracker.

Re: Exception in DT_2_IndicatePData

Hi Vasyl,

thank you for the investigation and proposed patch. I roughly looked over it a few days ago and it looks good. We will discuss the patch on Friday and I provide final feedback then.

Best regards,

Re: Storescu With TLS

Analogous to storescu's "--propose-..." flags, storescp has some "--prefer-..." flags, e.g.

Code: Select all

--prefer-jpeg8
. However, to be sure storescp "eats" everything just use

Code: Select all

--accept-all
flag and you should be able to accept any transfer syntax.

Re: Storescu With TLS

Hi, storescu cannot (de)compress images and per default only supports uncompressed transmission. Try option --propose-jpeg8 to also propose JPEG Baseline, or --required to propose whatever is required if you also have files that use a different compression scheme than JPEG Baseline. If you want cust...

Re: Storescu With TLS

Hi,

make sure you download the DCMTK binaries that include the SSL extensions, see DCMTK 3.6.7 - OpenSSL based security extensions on the download page.

Re: Memory Leak occurring When Inserting 1000CT Datasets in std::map

Hi,

I am not aware (at least) of any Windows-specific code in dcmdata's memory management, so I doubt the leak stems from DCMTK. If you can find the reason of the leak, let us know.

Best regards,
Michael

Re: Memory Leak occurring When Inserting 1000CT Datasets in std::map

Hi, I doubt that the leak comes from DCMTK. I used this main(), running 10 iterations only, on a directory with > 1100 DICOM files (up-to-date DCMTK code): int main(int argc, char* argv[]) { std::string dir_path = "/path/to/images"; std::vector<fs::path> pathList; std::copy(fs::recursive_d...

Re: DIMSE Failed to receive message (line=653)

Hi Arnauld, I agree with you that probably the conversion at the PACS side fails. Maybe your client could at least check the PACS logs to see how the PACS experiences this error. Also, if possible, get one of the affected DICOM files in original format (as it is stored in the PACS), if possible, by ...
