- W2082783785 abstract "Related to the demand for fast and efficient tomographic reconstruction methods, the interest for Direct Fourier (DF) methods, which have a reduced computational complexity, has been growing. In this paper we present a new NUFFT-based DF reconstruction method which can be directly applied to fan-beam CT data sets avoiding the interpolation in Radon space as well as the interpolation in Fourier space. The performance of the new algorithm, in ideal and noisy conditions, is compared to those of other well known reconstruction methods, revealing an excellent behavior, specially in noisy conditions." @default.
