Claim Text:
1. A method for reconstructing an image of an examination object from measured data, the measured data being captured during a rotating movement of a radiation source of a computed tomography system around the examination object, the method comprising: determining, by a control and computing unit, different iteration images of the examination object, successively, from the measured data by use of an iterative algorithm, during each iteration of the iterative algorithm, determining a next one of the iteration images based on the current one of the iteration images and the weighted current one of the iteration images, wherein an amount of reduction in noise associated with the current one of the iteration images depends on the location dependent contrast information, and a level of admixture of the current one of the iteration images and the weighted current one of the iteration images for determining the next one of the iteration images is determined using the variable.
