Is it possible to also provide the fan beam filtered backprojection jupyter code in 2D and 3D cases?

[tjk9501]

Recently I watched your videos about filtered backprojection introductions on youtube, and I have the following problems:

1. Did you have some easy-to-get-started resources about how to make fan beam filtered backprojection (FBFBP) code in Python or Jupyter Notebook? Because circular arrray setups are more frequently used in real life. I don't want to use matlab or python built-in functions because some important codes are hidden in those functions.
2. Did you have resources about how to extend the FBFBP technique to 3D imaging?

I would be grateful if you can provide the corresponding resources, thank you!
