A Comparison of Fast Factorised Back-projection and Wavenumber Algorithms for Sas Image Reconstruction
نویسندگان
چکیده
Abstract The Fast Factorised Back-Projection (FFBP) algorithm has received considerable attention recently for SAS image reconstruction. The FFBP algorithm provides a means of trading image quality and/or resolution for a reduction in computational cost over standard Back-Projection. In this paper we describe FFBP for SAS image reconstruction and compare it to the Wavenumber algorithm in terms of computational cost and image quality. The FFBP algorithm significantly out-performs standard Back-Projection. However, we have found that FFBP is out-performed by the Wavenumber algorithm. Further investigation is required to determine which algorithm is more desirable for motion compensation and multiple-receiver reconstruction.

Fast System Matrix Calculation in CT Iterative Reconstruction
Introduction: Iterative reconstruction techniques provide better image quality and have the potential for reconstructions with lower imaging dose than classical methods in computed tomography (CT). However, the computational speed is major concern for these iterative techniques. The system matrix calculation during the forward- and back projection is one of the most time- cons...

Introduction: Monte Carlo (MC) is the most common method for simulating virtual SPECT projections. It is useful for optimizing procedures, evaluating correction algorithms and more recently image reconstruction as a forward projector in iterative algorithms; however, the main drawback of MC is its long run time. We introduced a model based method considering the eff...
