Description: BACKPROJ uses the filtered or unfiltered backprojection algorithm to perform the inverse Radon transform. The filter is designed directly in the frequency domain and then multiplied by the FFT of the projections. The projections are zero-padded to a power of 2 before filtering to prevent spatial domain aliasing and to speed up the FFT.-BACKPROJ uses the filtered or unfiltered backprojection algorithm to perform the inverse Radon transform.

Description: 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.-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.
