Hi Jörg, Thank you for your quick reply. I quickly tried to run dcm2pnm as you mentioned. and got the message of the results, as follows; $dcmtk: dcm2pnm v3.5.4 2005-12-20 $ dcm2pnm: Convert DICOM images to PGM/PPM or BMP error: Invalid value for option --use-voi-lut (underflow: 0) Please tell me th...

Hello! Jörg, Thank you for your explanation. Soon after reading your reply, I tried confirming the handling of setVoiLut. Then I understood that the return value of setVoiLut is the same as "return VoiLutData->isValid()", so I believe that the obtained VoiLut is correct. BTW, it seems that...

Hello Jörg,

Thank you for your clear explanation.
I made sure that the pixel data stored in the DICOM file has already been applied modality lut to.
We (my co-workers and I) have been misunderstanding modality lut until now.
Thank you so much for your coorperation.

Bye,

Hi forks, I am not the person who sent this question originally. But I have a very simple and important problem. So, I would appriciate it if someone answer my question. I am tring to implement to apply PresentationLUT data from outside of the DICOM file to the DICOM image. But I don't know how to m...

Hello! Jörg, Thank you for your quick and friendly reply. From your suggestion, I understand that I made a mistake that the table No was wrong. I tried again and the results are as follows; table No -aa -bb -cc ----- 0 -----1 --1 --"E25" ----- 1 -----1 --0 --nothing In case of table No = 0...

Hello Jörg, Thank you very much for your reply. I understand that I was so comfused that the source code I created didn't meet our requirement. BTW, it seems that the default DCMTK doesn't apply the modality lut table in the DICOM file to the rendered data. Then, I tried using DcmPresentationState c...

Hello! I am tring to get ModalityLUT sequence from the DICOM file and apply the table data to rendered data using getOutputData(). Referring to dcmmklut.cxx, I implemented the source code, as follows; //ModalityLUT 1 DcmItem *ditem = new DcmItem(); DcmSequenceOfItems *dseq = NULL; DcmLongString moda...

Hello forks, Now I am wondering if VoiLut would be applied or not using DCMTK. In my source code, I implemented serching and appling VoiLut source code refering to Dimoimg.cxx and Dimoimg.h, as follows, //VoiLut 1 const unsigned long table = 1; OFString explanation; const OFBool ignoreDepth = OFFals...

Hi Per, Thank you for your information. We tried to use gdcmviewer, which is the brief viewer using gdcm and VTK, many times. But, unfortunately, it looks like it has the file size limitation, i.e. within about 6MB, because of the OpenGL issue. Then, we are suspisious of VTK having large data size l...

Hi Per, Thank you for your reply. As for the requirement to the new DICOM viewer, the first priority is fast processing. According to the voice from many customers, the process of rendering, moving and zooming must be real time. Multi function is preferable, e.g. moving, zooming, lut, movie, slide, ...

Hi Office-team, Your infomation is always very helpful for me. By the way, I have a question about DICOM viewer. We are developing new DICOM viewer and we are thinking that the combination of DCMTK and VTK is very effective. But, I think VTK is very strong tool for 3D rendering but its 2D viewer fun...

Hi OFFIC Team, Thank you for your reply. I had immidiately tried downloading the latest snapshot, but I could not find out the description in regard to BitsPerTableEntry and ELM_CheckValue. The compressed file name is "dcmtk_20080627.tar.gz", isn't it right? If so, please let me know where...

Hi OFFIC Team, The last week, I heard that dcmtk 3.5.4 has a bug about Palette Color. The phenomenon is that a certain Palette Color data is not properly displayed, because dcmtk interprets incorrectly the palette descriptor, the explanation is as follows; > Now the BitsPerTableEntry stored in the L...
