Paper Abstract

In many applications of computer tomography, it may be impossible to obtain projection data at all angles or there are opaque objects in the field. In such a situation we face a difficult problem to reconstruct a field from a set of incomplete projection data. Many techniques have been proposed to tackle these situations. In this paper, a modified Algebraic Reconstruction Technique is adopted and a attribute matrix is used to deal with the incomplete projection data by priori information. As an example, a symmetric flowfield in wind tummel is analyzed by this method.
