Abstract

A method is for correcting inhomogeneities in an image that is recorded from an examination object. The method includes recording an image to be corrected, calculating a correction image from the image to be corrected and correcting the recorded image with the aid of the correction image in order to produce a normalized image by multiplying the correction image by the image to be corrected. When calculating the correction images, the pixels in the vicinity of the imaged examination object are identified with the aid of a signal intensity that is lower than a limiting value. Further, these pixels are allocated signal intensities that in each case are a function of the signal intensity of the pixels in the respective neighborhood.
