Dear expert,

There is no PyTomography Extension in 3D Slicer version 5.8.1.

Please help me add it.

Thank you.

That is correct. There is no such extension available through the Slicer extensions manager. Are you thinking about [Add SlicerSPECTRecon extension by ObedDzik · Pull Request #2083 · Slicer/ExtensionsIndex · GitHub](https://github.com/Slicer/ExtensionsIndex/pull/2083) which is under review?

All Slicer Preview builds since about March 13th have the extension available to install.
