ART ( Algebra reconstructive memory Technique, ART ), namely the algebraic reconstructive memory technique. In the image reconstruction system, repetitive reconstruction manner is the absolute method for Gorden R. The algebraic reconstruction technique ( Algebra reconstruction Technique, ART ), and Gilbert P. The proposed joint iterative reconstruction algorithmic programic program ( Simultaneous algebraic Reconstruction Technique, SIRT ). The subsequent development of a variety of algorithms can be broadly divided into deuce categories: one is of two kinds of classical iterative correction, such as Eggerment P . B. ART in the Kacmarz iterative cash advance for set block shut circuit, Censor Y and Herman G . R. To further its improvement for variant block iteration, so that the classical iterative methods to devise a unified framework. Two by the Kashyap R L and Mittal M . C. Introducing optimization theory base iterative algorithm, intercommunicate from the measur ing process of random point of view, the image reconstruction problem is viewed as an estimation problem. Image reconstruction algorithm is essential, which optimized the prefatorial idea of the method is to select a intelligent impersonal lock and the objective function for the optimal value of the good algorithm.

For image reconstruction of the reasonable objective function: least squares method, token(prenominal) norm method, two power optimization, verbalise estimation, utmost likelihood, maximum a posteriori probability distribution method, minimum variance method and the maximum entropy method. But the particular(prenominal) choice of which mai! nly depends on the reconstruction of the object, but the algorithm is essentially a single objective optimization iteration algorithm. In recent old age Wang Yuanmei professor in checkup imaging field stray forward much touchstone image reconstruction theory. Algebraic reconstruction algorithm in order to improve the precision and convergence speed, the scholars in the fair ATR reconstruction algorithm is presented based on...If you want to get a full essay, order it on our website: OrderCustomPaper.com
