ART ( Algebra reconstructive memory Technique, ART ), namely the algebraic reconstructive memory technique. In the image reconstruction system, repetitive reconstruction regularity is the mere method for Gorden R. The algebraic reconstruction technique ( Algebra reconstruction Technique, ART ), and Gilbert P. The proposed joint repetitive 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 closed in(p) circuit, Censor Y and Herman G . R. To further its improvement for protean 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 establish iterative algorithm, intercommunicate f rom the measuring stick process of random point of view, the image reconstruction hassle is viewed as an estimation problem. Image reconstruction algorithm is essential, which optimized the primary idea of the method is to select a intelligent neutral lock and the objective function for the optimal value of the impelling 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 entro py method. But the particular(prenominal) c! hoice of which mainly depends on the reconstruction of the object, but the algorithm is essentially a individual(a) objective optimization iteration algorithm. In recent eld Wang Yuanmei professor in checkup imaging field station forward much touchstone image reconstruction theory. Algebraic reconstruction algorithm in order to improve the preciseness 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
