Matlab: inverse Radon transform
Hopefully someone know image processing toolbox well enough to answer my question!
I need to reconstruct an image from a sinogram, and I'm using the iradon(S,theta) function, where S is the sinogram image and theta is either a scalar or vector quantity of projection angles. However, we weren't given a set of projection angles to work with. Is there a way to look at the sinogram using image processing toolbox and extract the projection angle data?

Nevermind, I got it.
In case anyone is wondering,
find the length of the matrix that defines the sinogram,
then specify theta as going from 0:(length(S)-1), where S is your sinogram matrix.
Apparently in the newest version of image processing toolbox you can define your own theta and simply use more or less projections than the image gives you.
