In this paper we develop a new algorithm that enables the reconstruction of a region of interest (ROI) in Xray Computed Tomography (CT), when only a local region of the object is to be imaged. The method uses a Gaussian window function in order to reduce the X-ray attenuation from the region outside the ROI. The method uses almost completely local data and(More)
We present an algorithm which allows us to reconstruct a RegionOf-Interest (ROI) from transaxial truncated cone-beam projections. While sometimes it is possible to reconstruct good approximations from projections passing only through a specific localized region, in other cases the reconstruction of the original density function shows severe artifacts,(More)
We present an algorithm which allows us to investigate what is feasible when reconstructing a Region-Of-Interest (ROI) from transaxial truncated cone-beam projections obtained on a circular orbit in combination with information obtained at a different magnification level. We use the well-known fact that a rough estimate of the global properties of the Radon(More)
