Trying to writing a module for cross-sectional image reconstruction

Hi , First I want to thank you all for your wonderful app and incredible support ,
I a new to 3Dslicer and I wrote a python code for generating cross-sectional images . I am trying to build a module in 3Dslicer that gives 360 projection images as an input and after using the code renders the final 3D volume.
where should I start to do so ?

Maybe this will help:

Thank you very much for your help ,but I Have wrote a code similar to RTK and I would like to add it in 3Dslicer as an module ,how can i do that?
best regards
