None of my trials worked. Can you please check the files to see whether you can read them using DCMTK? http://rapidshare.com/files/164101677/orthodonty_forum.zip.html I am constantly getting segfaults but MATLAB can read and show the files, so I am assuming they are not corrupted. I create a DicomIm...

DiPixel::getData Segfault
Hello everyone, I have been reading DICOM images for a while (both single and multiframe), I just got another CT data but my code did not work for that. I debugged the code, the point where it crashes is: DicomImage *di = new DicomImage ( dfile, xfer, opt_compatibilityMode , 0, 0); ... const DiPixel...

First, I create a DicomImage. Then, I use getInterData() to get a DiPixel*. Next, I use getData() and cast the result to Uint16*, which is the original representation. Then, using VTK, I obtain a scalar pointer of type Uint16* to my image and fill it by using the casted values. Finally, I cast the v...

Might be shifted by one slice but I do not think that is much of a problem, it is clear that textures are totally different.

Yes, dcm2pnm works. I have uploaded two images, the output of my program and the output of MATLAB. Might give you an idea.

What additional information should I provide?

Displaying DICOM data
Hello everyone, I have a liver dicom file which I am reading with DCMTK and displaying with VTK. Unfortunately, some details which are not in the actual image show up, as I am checking it with MATLAB. I checked the byte order (LittleEndian, BigEndian) but there is no problem with it. I also changed ...

It is a little bit clearer now. I learned that there are 17 B-values and 17 DiffusionGradientOrientation vectors in this multiframe image. I am probably finding the first B-value and the DiffusionGradientOrientation whereas dcmdump reports some other values(probably the last). I mean, they are both ...

It seems a little weird to give a rapidshare link, but I could not think of a better alternative:) http://rapidshare.com/files/154652144/sample_multiframe.dcm.html For DiffusionGradientOrientation, I get -0.499998, -0.499998, -0.70711 but dcmdump gives 0.70584, -0.706335, 0.0536699. For DiffusionBVa...

Actually, I cannot say that I have understood what you mean. Following the example in the dcmdata documentation, I am trying to extract tags. Where do I exactly need to specify the sequence item? Here is the my whole code for the part that reads tags: DcmFileFormat dicom_img; OFCondition status = di...

Oh how can I not see that! Thank you very much Jorg. I have another question though. What does 'pos' exactly stand for? The documentation says 'index of the value in case of multi-valued elements (0..vm-1)' but I cannot get it as I am new in the field. I don't know the value I should use to extract ...

DiffusionBValue
I have previously stated my problem by replying to a relevant post but could not get an answer. So I am setting the same question forth: I am trying to read some tags from a Philips DICOM image. I am able to read simple tags like patients name, sex, etc. However, I cannot get DiffusionBValue and Dif...
