DICOM @ OFFIS

Why isnt it possible to calculate the upper limit? There is the pixel data after the VOI LUT transformation, why cant one look up the max/min values in this data, and use them as the bounds for Window Center? As I mentioned the same image is presented properly in other viewers, so there should be a ...

I have a DICOMDIR that I'm trying to load with DcmDicomDir. I can load it properly, but there is a crash in DcmDicomDir. here is the call stack and the link to download the DICOMDIR: http://dl.dropbox.com/u/1791478/DICOMDIR #1 0x0000000000768877 in DcmList::deleteAllElements (this=0x1282690) at dcli...

What for the clarification on Length/Center. But if I want to adjust them - how do I calculate the appropriate range of values for L/C? From what you have said it is possible that Window will span over negative values. But getOutputData guarantees that all pixel data is unsigned... Basically I want ...

Hi I'm using DicomImage::getOutputData() to read the pixel data and render it in my application. The problem is that the rendered image appears too bright for most of 16 bit CT images. I suppose that image Width/Center is not set properly, but the dicom tags for these values are present and set. Sho...

Yep, this is it - thanks a lot!
I'm wondering why it was not an issue on mac...

No, the same configuration compiles fine on Mac:
-L/usr/local/dcmtk/lib/ -lofstd -loflog -ldcmimage -ldcmdata -ldcmjpeg -lijg8 -lijg12 -lijg16 -ldcmimgle

I was trying to compile the project I'm working on under Ubuntu 10.04: $ gcc -v Using built-in specs. Target: x86_64-linux-gnu Configured with: ../src/configure -v --with-pkgversion='Ubuntu 4.4.3-4ubuntu5' --with-bugurl=file:///usr/share/doc/gcc-4.4/README.Bugs --enable-languages=c,c++,fortran,objc,...

Thanks!

Hi

The question is not directly related to DCMTK, but I could not find a better place to ask...

I'm looking for a sample of DICOM image files that cover all (or as many as possible) Transfer Syntaxes that the DICOM standard allows. Do you have something like this available?

Thanks!

Yep compiling the debug version of the library and looking at things in the debugger helped - I addressed this issue in another topic:

I think you are right, the registerCodecs functions were called during the initialization of the static class members, probably before the codecs lists were initialized.

Thanks for your response!

Ok, I managed to resolve this by calling the registerCodecs() functions at a later time in the applciation, but it looks weird.

I compiled the toolkit on windows with VS 2008 and I'm still observing the same problem. here is the call stack: > dcmtk-app.exe!OFCondition::OFCondition(const OFCondition & arg={...}) Line 343 + 0x11 bytes C++ dcmtk-app.exe!DcmCodecList::registerCodec(const DcmCodec * aCodec=0x006f6e30, const D...

Hi I was playing with DCMTK on my mac and run into some troubles registering the image codecs. When I call DJDecoderRegistration::registerCodecs(), this function in turn calls function DcmCodecList::registerCodec() which asserts on ln. 342 in dccodec.cc. It seems that the codeLock of OFReadWriteLock...

You are right, the problem was in the path to the dictionary... Sorry.. Now I have another problem - the application crashes on startup, when I make the following call. DJDecoderRegistration::registerCodecs(); more specifically, application breaks on ln 94 in diregist.h: static DiRegister Init_dcmim...
