Abstract:
1. A method of reconstructing images from data provided by at least one detector, comprising the steps of: moving a scanner along a first curve within a plane relative to a stationary object while scanning the object; scanning the object along a second curve within a plane transversal to the plane of the first curve; storing at least one cone beam projection in memory at a time; using at least one family of lines for the step of reconstructing; applying a convolution based shift invariant Filtered Back Projection algorithm to the cone beam projections of the first single curve and the second single curve; back projection updating the image of the scanned object and reconstructing an exact image of the scanned object with the convolution based Filtered Back Projection algorithm for circle and are cone beam computed tomography.
