DICOM @ OFFIS

thanks Marco

Hi there, I've found something weird while using DCMTK. I've received in my PACS some Waveform based DICOM object (twelveLeadECGWaveformStorage) and i've seen that, when i use DCMTK tools in order to change the Transfer Syntax from ImplicitLittleEndian to ExplicitLittleEndian of the DICOM object the...

Hi there, Just a question regarding with compression and Planar Configuration: I've recently seen that when I'm compressing and decompressing (via JPEG) a DICOM file (using the DCMTK tools for that purpose) they don't keep the initial Planar Configuration. What I was doing is compressing it and deco...

Hi michael, What u exactly mean with "an application to dump sample values to console"? like dcmdump does? I am interested in some kind of viewer of this type of objects...well not a viewer but maybe such a tool like "dcmwave-to-png" or any other imaging format? A 'visual' dump o...

Hi there, I have seen you have been investigating and working in the implementation of waveform data (such as vital sign data) into DICOM and that you included a DCMTK module for this purpose called dcmwave, right? I was interested in this since one of our investigation projects we are working in go...

thanks Marco

Hi Marco, thanks for your quick answer...yes, you are right the icon image is JPEG-embedded while the main dataset is uncompressed :shock: My answer here is, since i don't know a lot about it, is illegal to be in this situation (different encoding for different pixel data)? Shall both be of the same...

Hi there, I have found an issue (or that's what it seemed to me) while using the DCMTK tool for JPEG compressing: dcmcjpeg. The thing is that given an MG image (the problem is not focused in one image but generalized) that contain the element IconImageSequence (0088,0200), when i tried to compress i...

Many thanks Marco.

Hi there, I have been trying to add some private tags of my own using DCMTK to a DICOM file without success. I have firstly created a project with the mkdicbi.cxx file Then I modified the private.dic with the following: (0029,"XXX",00) UL MyGroupLength 1 (0029,"XXX",01) DS MinTem...

ok, Jörg, thanks for your time.

Hi there, I have reported some problems doing transformations with the DCMTK. Taking an image with Overlay tags, I managed to firstly compress it with dcmjpeg (doesn't care if it's Baseline, Lossless, Extended,...), then I decompress with dcmdjpeg and the final DICOM file result has lost the Tag (60...

Hello, Basically the dcmjpeg module was developed with lossy JPEG compression in mind, so the code performs certain preprocessing operations that are visually (but not mathematically) lossless prior to applying the compression algorithm itself That's really a pitty. I need to use lossless JPEG compr...
