ToolPythonBeginner CT reconstruction with scikit-image: a head slice from its projections sinogram = radon(phantom, theta=theta)sparse[n] = iradon(radon(phantom, theta=th), theta=th)sino = add_noise(radon(phantom, theta=th))clean = radon(phantom, theta=th)sino = add_noise(radon(phantom, theta=th), sigma=4 * SIGMA)
ConceptPythonIntermediate Filtered back projection: why the ramp filter sharpens a CT slice sino = radon(bead, theta)sino_phantom = radon(phantom, theta)image = iradon(radon(bead, th), th)
