| Abstract: | The most commonly used methods in CT for parallel beam projection data are the filtered backprojection (FBP) methods. (In some of the earlier literature these methods are also referred to as ˵convolution methods.″) The reason for this is ease of implementation combined with good accuracy. These methods are transform methods, where the taking of the derivative and the Hilbert transform is approximated by the use of a single convolution. [ABSTRACT FROM AUTHOR] |
