DCMTK读取DICOM文件，获取数据集、建立DicomDIr

?

Examples

The following example shows how to load a DICOM file and output the patient's name:

?

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

?The following example shows how to create a DICOM dataset and save it to a file:

?

char uid[100];DcmFileFormat fileformat;DcmDataset *dataset = fileformat.getDataset();dataset->putAndInsertString(DCM_SOPClassUID, UID_SecondaryCaptureImageStorage);dataset->putAndInsertString(DCM_SOPInstanceUID, dcmGenerateUniqueIdentifier(uid, SITE_INSTANCE_UID_ROOT));dataset->putAndInsertString(DCM_PatientName, "Doe^John");/* ... */dataset->putAndInsertUint8Array(DCM_PixelData, pixelData, pixelLength);OFCondition status = fileformat.saveFile("test.dcm", EXS_LittleEndianExplicit);if (status.bad())  cerr << "Error: cannot write DICOM file (" << status.text() << ")" << endl;

?The following example shows how to create a general purpose DICOMDIR from multiple files:

?

DicomDirInterface dicomdir;OFCondition status = dicomdir.createNewDicomDir();if (status.good()){  while ( /* there are files */ )    dicomdir.addDicomFile( /* current filename */ );  status = dicomdir.writeDicomDir();  if (status.bad())    cerr << "Error: cannot write DICOMDIR (" << status.text() << ")" << endl;} else  cerr << "Error: cannot create DICOMDIR (" << status.text() << ")" << endl;
