- W2373932149 abstract "In the technique of synchrotron radiation computed tomography(SR-CT),the filterd backprojection arithmetic and the iterative arithmetic are very typical two sorts of arithmetic.And their advantages and disadvantages are different clearly.In order to improve the quality of reconstruction images and reduce the computational time for SR-CT technique,a new arithmetic named mixed arithmetic is proposed in this paper.The reconstruction images acquired by the three sorts of arithmetic were compared and analyzed.The results indicate that the quality of reconstruction images from the mixed arithmetic is best.The mixed arithmetic not only includes the advantages of the filterd backprojection arithmetic and the iterative arithmetic,but also avoids their disadvantages.The important parameters in the mixed arithmetic such as the initial solution coefficient and the size of iterative step are also discussed in detail.And the relationship between reconstruction images quality and the two parameters above are given." @default.
