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

摘要

In method and apparatus for the reconstruction of images of a slice of an examination subject having a slice thickness with respect to an image plane from measured values acquired by a spiral scan of the examination subject with an x-ray source rotating around the examination subject with a detector having at least one line of detector elements, measured values lying within a maximum distance from the image plane are thereby involved in the reconstruction and are weighted such that a desired functional dependency of the slice thickness on the pitch is present.
