Hi
I am working dcmtk 3.6.0.

I need to insert meta header(DcmMetaInfo) tag 0002,0016 to dataset (DcmDataset)? Does it possible to do that? if yes how can i do that?

Thanks in Advance.

Hi,

do something like this (add error checks where necessary):

Code: Select all

DcmFileFormat dcmff;
dcmff.loadFile("file.dcm");
// Most relevant part:
dcmff.getMetaInfo()->putAndInsertOFStringArray(DCM_SourceApplicationEntityTitle, "DESIREDAETITLE");
dcmff.saveFile();

Best regards,
Michael

Hi

Not like that.

I have meta header information(8 elements) in DcmMetaInfo metaInfo variable.
I have dataset information (all dataset elements) in DcmDataset dataset variable.

now i need to insert 0002,0016 from metaInfo variable to dataset variable dataset without saving the file/image.

Did you get my problem? Thanks.

Hi,

yes, understood. But the tag 0002,0016 (i.e. group number 0002) is not permitted in a dataset according to the DICOM standard.

Otherwise just copy the value to any other tag:

Code: Select all

OFString val;
metainfo->findAndGetOFStringValue(DCM_SourceApplicationEntityTitle​, val);
dataset->putAndInsertOFStringArray(DCM_ImageComments, val);

Fell free to find another tag that makes more sense to you.

I think DCMTK will also accept

Code: Select all

dataset->putAndInsertOFStringArray(DCM_SourceApplicationEntityTitle​, val); 

but writing or transferring such a dataset is not standard conform, will not work or will cause errors at the receiver's side.

Best regards,
Michael
