Abstract
A computed tomography x-ray imaging system acquires a three-dimensional array of x-ray attenuation values using a cone beam x-ray source and a curved two-dimensional array of detector elements. Two-dimensional image slices are reconstructed using a filtered back projection method, and corrections are made to the images to account for incomplete data due to the cone beam geometry.
