CT Reconstruction: (Radon transform, Fourier Slice Theorem, & Convolution Backprojection)

You can use mathematical tools to reconstruct a 3D representation of the anatomy being image. This is done first by acquiring multiple 2D projection images from many angles. With this imaging principle, we acquire 3D images in medical imaging modalities such as Computed Tomography, Positron Emission Tomography, and Single Photon Emission Tomography.
