There is a method and a corresponding system for optimizing X ray imaging during a mammographic examination. In order to provide an optimization of X ray imaging in a first step (SOI) a breast (7) is compressed between a support plate (5) and a compression plate (3). In a next step (S03) a force height curve (13) is acquired during compression. Then in a further step (S05) an elasticity value of the breast (7) is determined radiation free based on the force height curve (13). In a further step (S07) a parameter of an X ray imaging system is optimized based on the determined glandularity (g). As the glandularity (g) of a breast may influence the attenuation of X rays the personalized setting of the parameters of the X ray imaging system may greatly enhance the image quality.
