## Abstract An algorithm of Dutt and Rokhlin (SIAM J Sci Comput 1993;14:1368β1383) for the computation of a fast Fourier transform (FFT) of nonuniformlyβspaced data samples has been extended to two dimensions for application to MRI image reconstruction. The 2D nonuniform or generalized FFT (GFFT) w

## Abstract Two processes of phase correction, Fourier phase mapping and secondβorder polynomial phase fitting, are compared in combination with four different schemes for Fourier reconstruction of asymmetric data, using oneβdimensional simulations and twoβdimensional human head data. Polynomial ph
## Background: Past receiver operating characteristic (roc) studies have demonstrated that single photon emission computed tomography (spect) perfusion imaging by use of iterative reconstruction with combined compensation for attenuation, scatter, and detector response leads to higher area under th
Long reconstruction times in three-dimensional (3D) positron emission tomography (PET) have long remained an obstacle to its routine clinical use. This article presents an experimental study of various algorithms on a compact parallel platform consisting of five hybrid nodes, each equipped with a Tr
## Abstract Significant research and development have been made on various kinds of CT's such as the Xβray, the MRI and the positron, which are applied widely in practice. The CT device is divided into the measurement system and the image reconstruction system. Efforts are still being made at prese
