Getting Patient Information from Image using CDLL..

If you have our Medical toolkit, you can use the L_DicomFindFirstElement() function to return a pointer to the first item in the Data Set with the specified tag.
After loading datase, You can use the L_DicomFindFirstElement() with the tags you need such as TAG_PATIENT_NAME and TAG_PATIENT_ID.

For more information about this function, refer to our help topic "L_DicomFindFirstElement" in our DICOM C DLL help topic.

Hello,

I am trying the following code:

LDicomDS*      pDS;
   pDICOMELEMENT  pRoot;
   pDICOMELEMENT  pElement;
   pDICOMTAG      pTag;
   L_TCHAR        szUnknown[]=TEXT("Unknown");
   L_TCHAR*       p;

   pDS = new LDicomDS(szFileName); //szFileName is the Path of the file{ C:\\test.dcm}
   pDS->InitDS( CLASS_NM_IMAGE_STORAGE, 0);
   pElement = pDS->FindFirstElement(NULL, TAG_PATIENT_NAME, FALSE);
   if (pElement != NULL)
   {
      pRoot = pDS->GetRootElement(pElement);
      
      pTag = LDicomTag::Find(pRoot->nTag);
      if (pTag != NULL)
      {
         p = pTag->pszName;
      }
      else
      {
         p = szUnknown;
      }
      MessageBox(NULL, p, TEXT("Notice"), MB_OK);
   }

But using this I am only able to get string i.e. "Patient Name", not the exact value of Patient Name i.e. "Kishore".

Can you please send me the correct code to get the value "Patient Name: Kishore" from the DICOM file?


Thanks...

I also try this one:

   HDICOMDS      hDS;
   pDICOMELEMENT pElement;
   pDICOMTAG     pTag;
   L_TCHAR       szUnknown[]=TEXT("Unknown");
   L_TCHAR       *p;

   hDS = L_DicomCreateDS(Filename);//"C:\\test.dcm"

   L_DicomInitDS(hDS, CLASS_XA_IMAGE_STORAGE, 0); 

   pElement = L_DicomFindFirstElement(hDS, NULL, TAG_PATIENT_NAME, FALSE);
   if (pElement != NULL)
   {
      pTag = L_DicomFindTag(pElement->nTag);
      if (pTag != NULL)
      {
         p = pTag->pszName;
      }
      else
      {
         p = szUnknown;
      }

      SendMessage(hDlg, LB_ADDSTRING, (WPARAM)0, (LPARAM)(LPCTSTR)p);

      pElement = L_DicomFindNextElement(hDS, pElement, FALSE);
   }

But still getting "Patient's Name" ,not the name of the patient exactly.

Please help me to come out of this.

Thanks

If you have not done so already, I would recommend checking out the help file topic Working with Data Sets in our C DLL help file. This will give you helpful information on navigating through and using DICOM Datasets with LEADTOOLS.

Once you get the particular element that has the data, you must then get the data from the element. The type of data will be specific to the element you have. Since you are getting the patient name, you should use L_DicomGetStringValue() after getting the element with the data you need.
