Convert a binary DICOM file
===========================
Binary DICOM files can be converted to their `JSON`_ or `XML`_ representation or recoded using another `transfer syntax`_ using ``odil transcode``.
Convert to JSON
---------------
Specify ``-f json`` to convert to JSON:
.. code-block:: console
$ odil transcode -f json file.dcm /dev/stdout
{ "00080005":{"Value":["ISO_IR 100"],"vr":"CS"}, ... }
If the output is to be read by a human being, the condensed format is not appropriate, and the result can be pretty-printed using the ``-p`` flag:
.. code-block:: console
$ odil transcode -f json -p file.dcm /dev/stdout
{
"00080005" : {
"Value" : [ "ISO_IR 100" ],
"vr" : "CS"
},
...
"00080016" : {
"Value" : [ "1.2.840.10008.5.1.4.1.1.4" ],
"vr" : "UI"
},
...
}
Convert to XML
--------------
Similarly, specify ``-f xml`` to convert to XML, with optional pretty-printing with the ``-p`` flag:
.. code-block:: console
$ odil transcode -f xml -p file.dcm /dev/stdout
<?xml version="1.0" encoding="utf-8"?>
<NativeDicomModel>
<DicomAttribute vr="CS" tag="00080005" keyword="SpecificCharacterSet">
<Value number="1">ISO_IR 100</Value>
</DicomAttribute>
...
<DicomAttribute vr="UI" tag="00080016" keyword="SOPClassUID">
<Value number="1">1.2.840.10008.5.1.4.1.1.4</Value>
</DicomAttribute>
...
</NativeDicomModel>
Change the transfer syntax
--------------------------
The transfer syntax of a file can also be changed through the ``-t`` flag with a `transfer syntax name`_:
.. code-block:: console
$ odil transcode -t ExplicitVRLittleEndian input.dcm output.dcm
$ odil print -H -u output.dcm | grep "Transfer Syntax"
Transfer Syntax UID 0002,0010 UI ['Explicit VR Little Endian']
.. _JSON: http://dicom.nema.org/medical/dicom/current/output/chtml/part18/chapter_F.html
.. _transfer syntax: http://dicom.nema.org/medical/dicom/current/output/chtml/part05/chapter_10.html
.. _transfer syntax name: http://dicom.nema.org/medical/dicom/current/output/chtml/part06/chapter_A.html
.. _XML: http://dicom.nema.org/medical/dicom/current/output/chtml/part19/chapter_A.html#sect_A.1
