Hi,

I have tried to test the modality response to foreign character sets.

My computer is set up to work with English and Danish settings. I have done a huge number of tests with ISO IR 100 (as needed to write some Danish Names) without problems.

My idea was that this testing could not be too difficult as the core challenge is just to enter some char values at the right place in the script. As I don't have a collection of keyboards I entered the language-specific characters into my scripts with a hex-editor. I think this method will still work when I reach the test of multi byte characters e.g. Chinese.

My first foreign language was Polish (ISO IR 101). In this case it worked fine. The letters were transferred via worklist and written nicely on the modality. Further I was able to check the perfect usage of the letters in the stored images.

Now I came to Russian (ISO IR 144). Worklist worked fine. The lettes looked as they should on the modality.
When I tried to store an image to DVT, using a script with the same char values as those sent in the worklist, DVT reported an error:
"Error: Could not check extended character set properties"�.
I guess this problem concerns a limitation of DVT or my DVT installation on a PC with only a few active languages.

My computer does not need to write Russian on the screen to make me happy. I just need to know that a set of char-values are presented exactly as in the script. Is it possible to make DVT accept all charsets? What do I need to change before DVT can compare Char-values of e.g. Russian?

Thanks in advance

Hi DVTk User,
DVT supports all extended character sets defined by DICOM standard. You can manually check the file "CharacterSets.dat" in DVT installation directory. Pl check the below snippet from file for ISO IR 144 character set:

DEFINE CHARACTER_SET "Cyrillic" CODE_EXTENSIONS
CODE_ELEMENT ("SINGLE", "ISO 2022 IR 144", "ISO 2022", ESC "02/13 04/12", "ISO-IR 144", "96", "G1", "Supplementary set of ISO 8859")
CODE_ELEMENT ("SINGLE", "ISO 2022 IR 144", "ISO 2022", ESC "02/08 04/02", "ISO-IR 6", "94", "G0", "ISO 646")
ENDDEFINE

DVT uses the escape sequence as defined for character set.
Pl send more detail for analysis.
