[Insight-users] wrap_itk, python, and dicom

[Mario Ceresa]

Hello David,

Which kind of information do you need to extract from the dicom header?

Basic info such as the dimensions or spacing are already available in
the getter methods of the image object (ex. image.GetSpacing() ).

To access the full dictionary my first thought was something like:

------------------------------------------------
import itk

reader = itk.ImageFileReader.ISS3.New(FileName='test_image.dcm')
reader.Update()

metad = reader.GetMetaDataDictionary()

print "List of all the key in the dictionary:"
print [str(key) for key in metad.GetKeys()]

print "Print the dictionary"
metad.Print(itk.cout)
------------------------------------------------

I can see the list of all the keys, but instead of printing their
value, the last method only shows:

[UNKNOWN_PRINT_CHARACTERISTICS]

Then I realized that gdcm comes with python binding itself. It might
be easier to read the dicom tag using directly those bindings.

Hope this helps,

Mario
