Hello guys,

I am trying to access the metadata of a loaded CT in an extension that I am writing in Python.  
For example i would like to the number of colums, rows and slices and the voxel sizes.  
How can I access this data?

Thanks a lot!

Have a look at [DICOM examples in the script repository](https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#DICOM_2) and let us know if you still have questions.

Thanks
