Abstract
A method for limited-angle sparse computed tomography (CT) reconstruction and is disclosed. The method involves: a) obtaining a sinogram image of an object from a limited number of scan angles; b) constructing sine waves represented in the sinogram image; c) superimposing the sine waves over the sinogram image; and d) creating a Hough Space representation to identify sinusoidal features in the sinogram image. A method for next scan angle prediction to identify and characterize stochastic, internal geometric features of an object is also provided. This method includes: a) identifying intersection angles for pairs of superimposed sine-like features, b) counting the number of intersections at each angle, c) calculating the distance of every unscanned angle from the nearest scanned angle, d) and calculating a score for each unscanned angle. The angle with the highest score is a candidate for the next scan angle. Error metrics for this method are also discussed.
