Generating reconstructed image from a sinogram without using 'iradon'

I am a graduate student and working in the field of medical imaging. I need to reconstruct an image from a sinogram, but can't use iradon. Is there any other way/ code to generating a reconstructed image, preferably using Filtered Back Projection method

Why can't you use iradon?

Hi Nisarg,

You might want to use IFANBEAM. Check out the help here : http://www.mathworks.com/help/toolbox/images/ref/ifanbeam.html

Also, you can find some useful resources on image reconstruction here: http://www.mathworks.com/discovery/image-reconstruction.html

HTH, Garima.
