The reduced datasets were then reconstructed with three different iterative reconstruction methods; the least squares implementation of the conjugate gradient method (CGLS) 35, the total variation ...
 AD Award Number: W81XWH-07-1-0324 TITLE: Quantitative ...
All reconstruction methods that we implemented can reconstruct the features in their correct layers and separate superimposed phantom structures along the Z direction, provided that accurate DTM system geometry is available. Our comparative study of multiple representative algorithms suggested that the two iterative methods,...
A comparative study of reconstruction methods applied to ...
Generally, iterative reconstruction methods have advantages over analytical algorithms, such as the widely used Filtered Back-Projection (FBP), when data are noisy and limited. This research is focused on the comparative analysis of different reconstruction techniques, aimed at finding the data processing procedure suitable for NT, that reduces ......

Qualitative and quantitative comparison between images ...
Background. Recently, iterative reconstruction with segmented attenuation corrections (IRSAC) has been introduced for reconstruction of 18 F-FDG PET images. IRSAC produces images that are more pleasing to the eye, but qualitative and quantitative comparisons between IRSAC and filtered back projection (FBP) have not been reported for metastatic cancer.

methods are used for this study (In the field of image reconstruction, FBP is a typical algorithm for directly negating forward operators, and PWLS is a typical iterative negation algorithm) illustrates the universality of local fusion of these algorithms.
A Motion Compensation Approach for Oral and Maxillofacial ...
the analytical algorithm (e.g. FDK), with a first-order motion compensation during the back-projection step, without introducing significant artifacts. When motion is large, a dedicated FDK 30,31 or an iterative reconstruction algorithm may be appropriate for the final motion-compensated reconstruction.
