119 Here is a sample Python plugin that registers a REST callback to dump
120 the content of the dataset of one given DICOM instance stored in
121 Orthanc, using `pydicom <https://pydicom.github.io/>`__::
122
123 import io
124 import orthanc
125 import pydicom
126
127 def DecodeInstance(output, uri, **request):
128 if request['method'] == 'GET':
129 instanceId = request['groups'][0]
130 f = orthanc.GetDicomForInstance(instanceId)
131 dicom = pydicom.dcmread(io.BytesIO(f))
132 output.AnswerBuffer(str(dicom), 'text/plain')
133 else:
134 output.SendMethodNotAllowed('GET')
135
136 orthanc.RegisterRestCallback('/pydicom/(.*)', DecodeInstance)

140 This can be called as follows::
