No Problem:-) I just saw, that you could have meant the explicit option "automatic data correction" from dcmodifys input options. This option (enabled per default) does some extra correction on tag values as said in dcobject.h: /** This flags defines whether automatic correction should be applied to...

Hi David, what kind of "tag values associated with the sequence length" do you mean? If you think of automatic group length or item length correction, the the answer is yes. The dcmdata routines automatically recalculate such values when writing the file. If you mean other values, please give me a h...

GCC on Mac OS X

Hi Bernd!

Just a note: I've tested DCMTK 3.5.4 on Mac OS X Tiger with gcc 4 (default). There you can compile the release without problems. Perhaps you're able to update your compiler to get DCMTK 3.5.4 working out of the box.

Best Regards,
Michael

Re: whats new for the wlmscpfs

Both tools support some new command line options (see manpages or documentation at http://support.dcmtk.org/docs ). Additionally some smaller changes and bugfixes were integrated. A complete list of changes can be found in the CHANGES.354 file included in the DCMTK source package ( http://www.dcmtk....

Hi Genghis,

try the other prefer-options (e.g. --prefer-jpeg8 for JPEG Baseline).

Topic: imagectn database limitations ?
Replies: 2
Views: 3123

Hi, the use of imagectn for 40.000 images and more is not recommended, perhaps not even possible. I can't say for sure, because I'm not very experienced with imagectn code. But there seem to be a few issues to consider: - If the index file reaches a size of 32MB, warnings are printed out to console ...

Hm, first you could use dcmdump from the DCMTK to check, whether your values are set correctly in the file. I'm not experienced with CT images, but you should check in part 3 of the standard, whether the possible values of "Pixel Spacing" are restricted for CT images.

Good luck,
Michael

Hi, Ah, I just discovered that it may be a part of the meta-header, that's why I can't modify it? Yes that's right. Dcmodify can't modify tags in the metaheader and the new dcmodify version in the upcoming release won't allow to specify such a command any more. Is there any way to modify it from a p...

Re: WindowCenter \ windowWidth

Hi,

perhaps section C.11.2.1.2 in part 3 of the standard might give the right answers;-)

Re: DCM_PixelSpacing

Hi, perhaps you only inserted only one value into the Pixel Spacing Attribute? It has a Value Multiplicity = 2, so you have to enter a pair of values there. In the DCMTK, attribute values with VM>1 are represented by a string with all its value parts separated by a backslash character. So the attrib...

Re: GSDF : getOutputData

Hi,

from viewtopic.php?t=363 :
[getOutputData()] transforms the stored pixel data according to the (grayscale) transformation pipeline as described in the DICOM standard (i.e. applies modality and VOI transform if applicable).

Hi Dave, Borland C++ Compiler is not actively supported by the DCMTK. However it should be possible to compile the toolkit using this compiler, too. The necessary code to extract tags from a DICOM file is contained in the module "dcmdata", which itself needs classes from module "ofstd". Using these ...

Hi David, every private tag you use in your dicom file must have a reservation context. This reservation tag looks like gggg,00xx, where gggg is a private (=odd) group number and 10<xx<FF. The tag gggg,00xx then reserves a range of private tags from gggg,xx00-gggg,xxFF for the private creator, that ...
