摘要
In a method for image reconstruction for a CT apparatus and CT apparatus for the implementation of such a method, acquisition of the data underlying an image reconstruction for an image plane at a specific position on the system axis ensues by combining measured values, for each individual projection angle needed for this image reconstruction, that are registered exclusively for this projection angle with different lines of detector elements, to form data apparently registered with a detector having only one line of detector elements, with a weighting of the measured values ensuing. The image reconstruction is then undertaken using a conventional algorithm for operating on data from a detector having only one line of detector elements.
