+Here is a sample Python plugin that registers a REST callback to dump
+the content of the dataset of one given DICOM instance stored in
+Orthanc, using `pydicom <https://pydicom.github.io/>`__::
+  
+  import io
+  import orthanc
+  import pydicom
+
+  def DecodeInstance(output, uri, **request):
+      if request['method'] == 'GET':
+          instanceId = request['groups'][0]
+          f = orthanc.GetDicomForInstance(instanceId)
+          dicom = pydicom.dcmread(io.BytesIO(f))
+          output.AnswerBuffer(str(dicom), 'text/plain')
+      else:
+          output.SendMethodNotAllowed('GET')
+
+  orthanc.RegisterRestCallback('/pydicom/(.*)', DecodeInstance)
