Hello. I have a problem. Many CT of russian patients have problem with PatientName.
I tried to use Dicompatcher, but it didn’t help.
I could find only one topic where one had problem with ??? in the patientname.
(link removed until it is confirmed that the files do not contain patient information)
Please help. What i am doing wrong? Thank you
Thanks for reporting, we’ll investigate and let you know what we find.
There is no 0x0008, 0x0005 attribute … but even worse, encoding is WINDOWS-1251. I have already seen such data set, with silent WINDOWS-1251 encoding.
The DICOM files have multiple sever DICOM non-conformities. The most serious are:
CharacterSet is not saved in the file. It seems that the file uses Windows-1251 code page, which is not even a valid DICOM character set.XRayTubeCurrent field is stored incorrectly (it must be an integer value, the value is 4.1 - see David Clunie's Blog: The DICOM Exposure attribute fiasco)There are also some incorrectly generated UIDs.
I would recommend to contact your device manufacturer and report these errors.
That said, I’ve added two rules to the DICOM patcher that can fix the two serious issues. It will be available in Slicer Preview Release that you download tomorrow or later. Enable Fix invalid exposure tags and Specify character set with cp1251 parameter.
I installed and try to patchdicom. I had no effect. I can’t find " Fix invalid exposure tags and Specify character set

Please use the very latest Slicer Preview Release (that you have downloaded today).
Hello. I tried to make friends with 3dslicer again. Cyrillic symbols dont works in many ct’s. And i found that filepath don’t works with cyrillic symbols. video describing errors and files
The files that you attached suffer from the same issue (incorrect SpecificCharacterSet value) as those that you provided earlier. Please contact the manufacturer of the device/software that produced these files, as they are incorrect.
DICOM patcher’s Specify character set rule fixed most of these files, except those where the SpecificCharacterSet field was not just missing, but it contained incorrect value. I’ve submitted a pull request that makes the patcher rule even stronger - if that is integrated then the Force character set rule will become available in DICOM Patcher module and you can fix all these flawed files and load them into Slicer with correct patient names.
Loading files that are stored in path that contained special characters: I’ve already submitted a fix, but it has not been integrated yet. @jcfr please have a look.
