/diy/ - Do It Yourself

Maybe you didnt see my post, Astra-toolbox is very good.
It can do forward projection on a 3D or 2D array, to simulate a CT scan of an object and you will get the simulated projected images, what you would capture with a detector. Of course the physics interactions are not there (Compton scattering, beam hardening, accurate attenuation). And then it can do backprojection from projections to get the reconstructed 2D 3D array of your thing. It can also do reconstruction from non uniform angles. Lets say your system is not perfect, but you can

>visible light ct scanner
As other anon said, its a pain, too much reflection. Other than laying down the control foundations for a CT scanner i see no point dealing with visible light like that.
I can provide you with real projections of scans if you want.

>reflection is significant if you're imaging someone with metal implants
Its is a problem, even metals in polymer are a pain. Reflection has a small effect, the problem is the density difference and the mathematics behind it. In short, the bigger the density difference the worse the interface will be between the densities. Pic related is a screw in a plastic pipe and wood. Detail is lost around the metal part completely.
