Re: How to modify sequence in multiframe
Thank you. Let me clarify my question: how to erase items in sequence ? For example I have CT multiframe. The details of each frame are given in DCM_PerFrameFunctionalGroupsSequence, in this sequence there are some items like DCM_CTExposureSequence. As soon as I reduce number of frames I have to era...

Or perhaps I have to ask what for an approach should be used reduce amount of frames in multiframe CT ...

Re: How to write tag to multiframe
Thanks a lot, it works, I've changes 4th parameters to "false" as in call Dataset->findAndGetSequence(DCM_PerFrameFunctionalGroupsSequence, dcmSqPerFrame, true, false).good() so in call item->findAndGetSequence(DCM_CTExposureSequence, dcmSqCTExposure, true, false).good() obviously omitting...

Dear All, I try to write tag to CT multiframe, namely DCM_XRayTubeCurrentInmA. This tag in my file is twice wrapped in sequence. This is my code: DcmFileFormat fileformat; if (fileformat.loadFile("D:/xxx/test.dcm").good() cout << "File opened \n" << endl; else { cout << cout << &...

How to get number of instances in study from PACS?
I use sendFINDRequest to look for studies in PACS and use its result in sendCGETRequest to download studies from PACS. It works, but before starting to download I need to know how many instances (dicom files) are in study ? Like in case of CT modality for example?

Re: getOutputData question - not correct output
Vielen Dank!

getOutputData question - not correct output
Dear Sirs, I try to get b/w CT image from dicom by function int DicomImage::getOutputData (void *buffer, ...) The values of HU units in all pixels in image are by value 32768 = 2^15 bigger than correct values. In other words the result of getOutputData shifted by the same value 32768 = 2^15. The dic...
