Example showing differences between filtered backprojection (right half) and<unk>  method (left half)<unk>  refers to<unk>  algorithms used to reconstruct 2D and 3D images in certain imaging techniques. For example, in computed tomography an image must be reconstructed from projections of an object. Here,<unk>  techniques are usually a better, but computationally more expensive alternative to the common filtered back projection (FBP) method, which directly calculates the image in a single<unk>  step. In recent research works, scientists have shown that extremely fast computations and massive parallelism is possible for<unk> , which makes<unk>  practical for commercialization.
