DICOM @ OFFIS

Hi, I am trying to insert our propreitary tags in DICOM dataset using Leadtools. I am giving proper value representation for the tags. But most of the private tags value is displayed as unknown in dcmdump and i am unable to read the private tags using DCMTK, becoz it says unknown value and returns n...

Hi, I have a dataset which contains the metaheader tags also. when i try to save the dataset into file i get the repeated meta header tags. How i am doing it is.... MVUFile1 = new DcmFileFormat(tempDS); RetVal = MVUFile1->saveFile(DestFile, opt_ixfer, EET_ExplicitLength, EGL_recalcGL, EPD_noChange, ...

hi,

can i read a bitmap file using DCMTK lib. I want to read the bitmap file without using any windows lib.

Can anyone help me in doing this?

hi, I need to get the image data for the selected part of a image and display it as a bitmap. So i need to get a bitmap handle for that. Like in LeadTools we have an option to go for BitmapHandle, do we have an equivalent for that in DCMTK. Or can u give me any idea of how to do that with DCMTK to f...

hi Marco,

yes, i tried with dcmdrle in --verbose mode, it also returns "Pixel representation cannot be changed". I think something is wrong with the image itself. anywhere thank you for your reply.

hi Marco, Ya, I am registering the rle decoder before calling choose representation.I am following the same procedure as i posted in my previous topic. Here is the procedure i am following in getting the uncompressed file: DcmRLEDecoderRegistration::registerCodecs(opt_uidcreation, opt_verbose, opt_r...

hi, I am trying to convert the RLE compressed to little endian . chooseRepresentation is failing to get the pixel representation of little endian. May i know in what circumstances do i get that error. I tried using dcmdrle also, it also returns that "Pixel representation cannot be changed"...

Hi Marco,

Thanks for your clarification.

hi Michael, I tried using dcmdrle for decoding the rle compressed images. The uncompressed images appear as the same as old ones. i.e., the image appear as if they are missing the palette. I don't say exactly that is about palette but the monochrome image appear completely with out the gray scale. B...

Hi Michael,

Thanks a lot for your response. I am trying to use dcmdrle now, and i will let you know the result.

I am using Dicom works viewer. I will check all the three possibilities if it is repeating again.

Thank you,

Hi Michael, Thanks for the response. As you said, the image has the photometric interpretation as "PALETTE COLOR". All the tags and their values are same after decoding RLE compressed image. I have a question, when we are not changing any tag values, why the image when displayed looks like...

hi,

I am trying to change the transfer syntax from RLE compressed to explicit little endian using RLEDecoder. It Successfully converts, but the palette data is missing.

So, the images are not proper in the converted file.

can anyone tell me what should be done to overcome this.

thanks.
