To implement projection the simplest way is to rotate your image then sum over a row or column. The simplest way to implement back projection is to take a line of your sinogram which is a projection from certain view (angle) then repeat that line to form an image then rotate that image regarding the projection view, then sum all of backprojected views. There is ana unique formula for continuous case but for discrete case there there are many different implementation, thethis one i told here is the simplest.

Good luck.
