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 [(13)] and a curved two-dimensional array of detector elements [(16)]. Two-dimensional image slices [(55)] are reconstructed using a filtered back projection method, and corrections are made to the images to account for inaccuracies in the reconstruction method and for incomplete data due to the cone beam geometry.
