Hello @a10227,

This has to do with the non-isotropic pixel spacing in your data. This is very common in medical imaging and microscopy. ITK-SNAP accounts for this during display. In your display you just retrieved the pixels without taking spacing into account. This is discussed in the [Fundamental Concepts page](https://simpleitk.readthedocs.io/en/master/fundamentalConcepts.html) and in [this Jupyter notebook](https://github.com/InsightSoftwareConsortium/SimpleITK-Notebooks/blob/master/Python/05_Results_Visualization.ipynb). The latter includes a function `make_isotropic` which you can use to enable correct display of your images in a notebook.
