Set of functions performing ct reconstruction tasks like a radon transformation, a simple backprojection, a filtered backprojection using a convolution in the spatial domain, a filtered backprojection using a 2D Fourier transformation, and a filtered back projection using the central slice theorem.
It includes the function
myCtRecontruction
that should run out of the box and uses Matlab's Shepp Logan Phantom for demonstration. It is also possible to run the myCtReconstruction with an argument
myCtRecontruction(anyCtDataSet)

to perform image reconstruction on a custom data set.
