Hello,

I am trying to use the PyTomography extension with **3D Slicer version 5.12.2** , but the extension does not work. It appears to be incompatible with this version of Slicer.

Could you please confirm whether PyTomography currently supports Slicer 5.12? If not, are there any plans to update the extension for compatibility with the latest Slicer release?

If there is a recommended Slicer version that works reliably with PyTomography, I would appreciate your guidance.

Thank you for your excellent work on this project.
