Re: Getting file id from DICOMDIR

#3 Post by samnaction »

I have written the following code to get the filename. Is there any other efficient way instead of looping ?

Code: Select all

void readDICOMDIR(const char* dir)
{
	DcmDicomDir dicomdir(dir);
	DcmDirectoryRecord *   root = &(dicomdir.getRootRecord());
	DcmTag refFileTag(DCM_ReferencedFileID);
	if (root != NULL)
	{
		
		DcmDirectoryRecord *   PatientRecord = NULL;
		DcmDirectoryRecord *   StudyRecord = NULL;
		DcmDirectoryRecord *   SeriesRecord = NULL;
		DcmDirectoryRecord *   FileRecord = NULL;
		OFString            tmpString;
		std::vector<std::string> fileName;
		if (root != NULL)
		{
			while (((PatientRecord = root->nextSub(PatientRecord)) != NULL))
			{
				while (((StudyRecord = PatientRecord->nextSub(StudyRecord)) != NULL))
				{
					
					while (((SeriesRecord = StudyRecord->nextSub(SeriesRecord)) != NULL))
					{
						
						while (((FileRecord = SeriesRecord->nextSub(FileRecord)) != NULL))
						{
							if (FileRecord->findAndGetOFString(DCM_ReferencedFileID, tmpString).good())
							{
								fileName.push_back(std::string(tmpString.c_str()));
							}
							
						}
					}
				}
			}
		}

	}
}

Hi,

you could use DcmItem's findAndGetElements() to retrieve all occurrences of a tag.

I think you must load it as a regular DICOM file/dataset (not via DcmDicomDir), i.e.

Code: Select all

DcmFileformat dcmff; 
dcmff.loadFile("DICOMDIR"); 
dcmff.getDataset()->findAndGetElements(....)
...
Best regards,
Michael
