DcmTag

[kattabomane]

Hello,
I am not yet familiar with the DCMTK.
I have a small stupid question.
I have taken an example from the help :

Code: Select all

#include "dcfilefo.h"

DcmFileFormat fileformat;
OFCondition status = fileformat.loadFile("test.dcm");
if (status.good())
{
  OFString patientsName;
  if (fileformat.getDataset().findAndGetOFString(DCM_PatientsName, patientsName).good())
  {
    cout << "Patient's Name: " << patientsName << endl;
  } else
    cerr << "Error: cannot access Patient's Name!" << endl;
} else
  cerr << "Error: cannot read DICOM file (" << status.text() << ")" << endl;

The compiler says DCM_PatientsName is an unidentified identifier. Where is this defined ?
How to convert OFString to CString ?
Thanks for your help.

The standard tags are defined in "dcmdata/include/dcdeftag.h". Just include "dctk.h" instead of "dcfilefo.h" and it should work.

With regard to your second question: I don't know. Please refer to the documentation of both classes. For example, OFString::c_str() returns a "const char *".

Hello,
Thanks for your help. It solved my problem.
But why can't i get the dicom tags (0002,XXXX) ?
Otherwice i am able to read all other tags.
Is there any reason ?
Thanks

The attributes of the 0002-group are contained in the metaheader of the file, not in the dataset. Use

Code: Select all

fileformat.getMetaInfo()->findAndGet...

instead of the method to get a file's dataset.
