ABSTRACT:
In a method for compensating a sensitivity profile of an antenna arrangement which is visibly manifested in a nuclear magnetic resonance image, respective source nuclear magnetic resonance images of the same image subject and respectively composed of picture elements are registered with two antenna sub-arrangements arranged opposite one another, and brightness values are allocated to the picture elements of the source nuclear magnetic resonance images dependent on the image subject. A geometrical average of the brightness values of picture elements of the two source nuclear magnetic resonance images respectively corresponding to one another is formed. Corresponding picture elements of a single compensated nuclear magnetic resonance image are formed dependent on the geometrical averages.
