DICOM @ OFFIS

Hi All, I am trying to break US modality's multiframe Dicom file into single frame dicom files, which contains 522 frames. Earlier i am loading one frame at a time by passing fCount as 1 ,it was taking 31 secs break all frames into single frame Dicom files. Code: u_int PartialFetchCount = 1; DicomIm...

Hi,

We have some 32 bit RT Dose Files. As i know, DCMTK compression API's are meant for 8 and 16 bit DICOM files. I have seen DICOM RT support in recent dcmtk snapshot. Can you please confirm that 32 bit RT Dose files compression is supported in the snapshot?

Thanks,

Hi, When i am accessing pixel data for the few frames in multiframe image getting exactly half of original Pixel data, I am using getInterData() API after that I am using getRepresentation() API to get the Pixel data Representation it is returning 8 bit even though it is 16 bit frame. so that I am g...

Hi All, I have some XA modality DICOM files where DCMTK chooseRepresentation() APi is returning "Can Not Change Representation". I found there is Icon Image Sequence tag present in these DICOM files. Following is the dump for that dicom file : (0088,0200) SQ (Sequence with explicit length ...

Hi All, We are migrating our applications from VS 2005 to VS 2013. On Windows 8, x64 machines, DCMTK saveFile() API is crashing. I created one small application which will only dump patient name in dicom file. DcmFileFormat fileformat; DcmDataset *dataset = fileformat.getDataset(); OFCondition statu...

Hi J. Riesmeier, Sorry for late responding. As you mentioned in your last post, that the Pixel Data is not encoded according to the transfer Syntax specified in the file meta information header. Can you please help me to figure out in which format they have encoded Pixel Data ? I know that these DIC...

Hi J. Riesmeier, The sceanriou is : we are working on an inquiry where we have to migrate the data from old GE PACS (pathspeed). The archived data is in PLASOM MODs (5.25 inch) with 5.4GB capacity. The client has given us 2-3 MODs and asked us to demonstrate the capability for data migration. We are...

Hi All, I have some dataset from GE PATHSPEED 7.12 and i need to parse those files. DCMTK loadFile() API is returning me following error : PixelData (7fe0,0010) larger (5841768) than remaining bytes in file. I google it and found that GE PATHSPEED 7.12 PACS have some proprietary compression techniqu...

Hi All, I have tried to implement JPEG 2000 compression logic using OPENJPEG library. For most of the cases, it worked fine. But for studies with IconImageSequence , its crashing. FOllowing is the ImageIconSequence tag : (0028,0002) US 1 # 2, 1 SamplesPerPixel (0028,0004) CS [PALETTE COLOR] # 14, 1 ...

Hi All, We have written one multi-threaded application to parallely compress the dicom files(using multi-threaded dcmtk). I found it somehow slow. Following is the code : DcmDataset *dataset = fileformat->getDataset(); DcmXfer original_xfer(dataset->getOriginalXfer()); DcmXfer opt_oxferSyn(opt_oxfer...

Thanks

Hi,

Thanks for quick reply.

Any idea in which release(or version) you guys are planning to provide this Compound Graphic Objects support.

Is this feature available in latest dcmtk snapshot?

If not, can you please suggest me any work around?

Thanks,
