Comparative study of different image reconstruction methods
Algebraic reconstruction technique of iterative reconstruction projection is defined in terms of system of linear equation. Many analytical and iterative methods are available. In this paper FBP analytical method and different iterative methods (kaczmarz, randomize kaczmarz, L 1 and L 2 norm) are used to reconstruct the image....
Quantitative Comparison of Analytic and Iterative ...
The purpose of the present study was to assess the quantitative accuracy of both iterative reconstruction and 3D acquisition for cardiac PET studies. To this end, an interleaved 2D/3D scan protocol was used to enable comparison of 2D and 3D imaging within the same patient and study, and data were reconstructed with both FBP and OSEM.
for reconstruction of structural defects A novel ...
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.
