How to use 1D projections to reconstruct an image?

12 views (last 30 days)
Assuming I obtain 180 projection data values from the rotation of a source and detector from 0 degrees to 180 degrees, how can I use the 1D projections to reconstruct an image ? At this point I still do not have any code as I can not figure out the geometric aspect of each point along the trajectory of a projection.

Sounds like a job for iradon

This is essentially what CT does. You need to do filtered back projection. Study up on CT and find out how to use the inverse radon transform and how to filter it.
