Hi Dhaval,

As i remember there are a post here discussing about modifying dicom tag, perhaps you can use those approach to add new tag into you dicom file.

[dhaval joshi]

Here some code to modify tag, hope it help.

public static void changementTag(File file, int tagChooser, String aModify, VR vr, String newString )
    {
        try
        {
            DicomInputStream dis = new DicomInputStream(file);
            DicomObject dio = dis.readDicomObject();
            dis.close();
           
            String fileName = file.getAbsolutePath() + ".ori";
            File originFile = new File(fileName);
            file.renameTo(originFile);
           
            boolean change = false;
            dio.putString(tagChooser, vr, newString);
            change = true;
           
            if(change)
            {
                FileOutputStream fos = new FileOutputStream( new File(file.getParent()+ "/" + file.getName()));
                BufferedOutputStream bos = new BufferedOutputStream(fos);
                DicomOutputStream dos = new DicomOutputStream(bos);
                dos.writeDicomFile(dio);
                dos.close();
                originFile.delete();
            }
        }
        catch(IOException ex)
        {
            ex.printStackTrace();
        }
    }


P.S : I've forgot which post discussing about it, so i post the code instead.

You can try attribute coercion using a cstorerq.xsl file in the conf/dcm4chee-ae folder. Sample in conf/dcm4chee-ae/MOD_AET 

[dhaval joshi]

How should I do it, can you give me example, below is what I see in cstorerq.xsl

      <xsl:variable name="reqPhysician" select="attr[@tag='00321032']"/>
      <xsl:variable name="reqService" select="attr[@tag='00321033']"/>
      <xsl:variable name="reqProcDesc" select="attr[@tag='00321060']"/>
      <xsl:variable name="reqProcCodeSeq" select="attr[@tag='00321064']"/>
      <xsl:if test="$reqPhysician or $reqService or $reqProcDesc or $reqProcCodeSeq">

[jne...@gmail.com]

Try this:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:output method="xml" indent="no"/>
  <!-- overwritten by application with actual values -->
  <xsl:param name="calling" select="'SAMPLE_MOD'"/>
  <xsl:param name="called" select="'DCM4CHEE'"/>
  <xsl:param name="date" select="'20051206'"/>
  <xsl:param name="time" select="'115600.000'"/>
  <xsl:template match="/dataset">
    <dataset>
      <attr tag="00080005" vr="CS">ISO_IR 100</attr>
    </dataset>
  </xsl:template>
</xsl:stylesheet>

Does't work, Below is how my file looks like

<!--

on root level to item of Request Attributes Sequence (0040,0275), which is
extracted into DB series record by default attribute filter configuration.

        <!-- (0040,0275) SQ #-1 Request Attributes Sequence -->
        <attr tag="00400275" vr="SQ">

If you want the changes to be made to the files on disk, as opposed to only in the database - change CoerceBeforeWrite to True in the service=StoreScp mbean in the jmx-console.

Also check and make sure that you have put the cstorerq.xsl file in the correct location. Placed directly under server/default/conf/dcm4chee-ae - it applies to ALL images received. Placed under server/default/conf/dcm4chee-ae/AETITLE/ - it will apply only images received from AETITLE.

It may also be that you need to have the tag defined in the dcm4chee-attribute-filter.xml in order to be able to coerce it - check the file server/default/conf/dcm4chee-attribute-filter.xml.

If still stuck after that - you can turn on coercion logging in the service=StoreScp mbean as well, and look at the logs generated under log/coercion. The files will look something like:

20130218142611.706.out-cstorerq.xsl.in
20130218142611.706.out-cstorerq.xsl.out

Dhaval, could you share how you create/modify the xsl file and where you place the file?

Thanks,

[Dhaval Joshi]
