Title: Method for the reconstruction of images from measured values acquired with a CT apparatus by spiral scan and CT apparatus for the implementation of the method

Abstract: In a method and computed tomography (CT) apparatus for the reconstruction of images from CT measured values acquired by spiral scan that are respectively allocated to one of a number of projection angles and a z-position on the longitudinal axis of the spiral scan, for each projection angle, all measured values belonging thereto and to the corresponding complementary projection angle and lying within a maximum spatial distance from the image plane, and lying within a maximum time from a reference time, are employed in the reconstruction, respectively weighted according to their spatial and time position.
