Abstract

A new method for image reconstruction from smaller view angle projections less than 180 degrees, is reported. This method does not include any missing projection data estimating processes, which are often seriously jeopardized by the presence of a slight fluctuation component. In this algorithm, the projection function is expanded by using complete functions, which can compose an orthogonal set on the projection allowed data variable region. These orthogonal functions are analytically extended to the outside variable area, where the projection data are not available, and the whole object functions are obtained. Computer simulations were carried out to demonstrate the effectiveness of the method. Some practical algo-rithms for the real data calculations are also presented.
