Read the contents of a private dicom tag with dcm4che2 toolkit

[Thanasis Iliopoulos]

My question is quite simple: How can i read a private dicom TAG (e.g. 0019,105A) ny using the dcm4che2 toolkit?

I am able to parse/read "public" dicom tags by using:

try {
            DicomObject dcmObj5;
            DicomInputStream din5 = null;
            din5 = new DicomInputStream(file);
            dcmObj5 = din5.readDicomObject();
            tmpSeriesId = dcmObj5.getString(Tag.SeriesInstanceUID);
            din5.close(); 
    }
        catch (IOException e) {
                e.printStackTrace();
    }

Can i use somehow getString() to read a private dicom tag?

We can put

 tmpSeriesId = dcmObj5.getString(0x00020010);

My solution is following ;

try {
            DicomObject dcmObj5;
            DicomInputStream din5 = null;
            din5 = new DicomInputStream(file);
            dcmObj5 = din5.readDicomObject();
            tmpSeriesId = dcmObj5.getString(0x00020010);
            din5.close(); 
    }
        catch (IOException e) {
                e.printStackTrace();
    }

Thanks Dimitri!

An elementary question:

If for example if want to read the private TAG:  0019,105A

How the representation of form: 0x00020010 is derived? For tag: 0019,105A

i would use:

tmpSeriesId = dcmObj5.getString(0x019105A);

??

Use code following :
File input = new File();

DicomObject dcm = readDicomObject(input); 

String tmpSeriesId = getHeaderStringValue("0019,105A");

 

My codes : 

         /**
         * Read the file into a dicom object
         * @param f the dicom file
         * @return the read dicom object
         */
        public static DicomObject readDicomObject(File f) {
            DicomObject dcmObj;
            DicomInputStream din = null;
            try {
                din = new DicomInputStream(f);
                dcmObj = din.readDicomObject();
                return dcmObj;
            }
            catch (IOException e) {
                e.printStackTrace();
                return null;
            }
            finally {
                try {
                    din.close();
                }
                catch (IOException ignore) {
                }
            }
        }

/**
         *reads the tag (group,element)
         * @param headerNr e.g. "0018,0050" to get Slice Thickness<br>
         * @return String
         * @throws DicomHeaderParseException
         */
        public String getHeaderStringValue(String headerNr) {
            headerNr = headerNr.replaceAll("xx", "00").replaceAll("XX", "00");
            return getHeaderStringValue(toTagInt(headerNr));
        }

 /**

        public static int toTagInt(String headerNr){
                return Integer.parseInt(headerNr.replaceAll(",", ""), 16);
        }
