multiframe dicom image

Hi ! I have a multiframe dicom file ( Philips MR ) and i want to understand multiframe file structure exacty. My question is; When looking at the header, there is a <0x5200, 0x9230> (Per Frame Functional Groups Sequence) tag. Inside this sequence tag, there is an item for each frame. There is also a...

Hi Jörg, As you said I read part 3 of the standard but I still couldn't figure out exactly, how to read attributes from a multi-frame MR image, especially attributes in Per-frame Functional Groups Sequence Attribute (5200,9230) for each frame using DCMTK (for example Dcm_WindowCenter and Dcm_WindowW...

Thanks, and I have another immedate question. I have a multiframe image in a single file. There are 1020 slieces. I want to read DCM_PixelSpacing for slices. When I check the file header I see for each slice there is a seperate (0028, 0030) Tag. I cannot get the tag value by using both following cal...

Does it mean that for all RGB images, R, G, B components are represented each by 8 bits,
even after all transformations (Modality, PS, LUT, etc..) applied and image rendered by DicomImage ? So there is no meaning of calling getOutputData(17/* or something > 8*/)
for an RGB image?

Yes, I am sure
My file is at http://rapidshare.com/files/190983032/cardio.dcm.html
When I call di->getOutputData( 8 ), i cannot display anything, but calling di->getOutputData(17) displays image prfectly. But, I have forgotten how I got 17:(

Dicom RGB Image and DicomImage::getOutputData()

Hi, I have such a problem: I was trying to display a DICOM image whose photometric interpretation is RGB. Image has dimentions 1000x1000. I have the following code snippet: di = new DicomImage(dfile, xfer, 0UL, 0UL, 0UL); EP_Interpretation epi = di->getPhotometricInterpretation(); const DiPixel *dmp...
