摘要： The present invention relates to mammography. In particular, the present invention relates to a method and a corresponding system for individually monitoring a compression force in an apparatus for mammographic examination for personalized compression guidance. In order to provide a personalized guidance for the compression of the breast in a first step (S1a, S1b, S1c) a breast contact area (A) between a breast under examination and a compression plate (3) or a support plate (15) is determined. In a next step (S5) a compression force limit is determined based on the breast contact area (A). Then, in a further step (S9a, S9b, S9c) an output signal (5) representative of the relation between the breast contact area (A) and the compression force limit is provided to a user such that the user may decide whether to complete or to continue the application of compression force.

摘要： The present invention relates to X-ray imaging technology as well as image post-processing. Particularly, the present invention relates to a method for computer aided detection of structures in X-ray images as well as an X-ray system. A computer aided detection algorithm visibly determines tissue structures in X-ray image information and subsequently matches the shape of a determined tissue structure with a library of known tissue structures for characterizing the type of determined tissue structure. The determination of a tissue structure and thus the characterization of the type of the tissue structure may be enhanced when employing also spectral information, in particular energy information of the acquired X-ray image. Accordingly, a method (70,80,90) for computer aided detection of structures and X-ray images is provided, comprising the steps of obtaining (72) spectral X-ray image information of an object, wherein the spectral X-ray image information constitutes at least one X-ray image, detecting (74) a tissue structure of interest in the X-ray image by employing a computer aided detection algorithm, wherein detecting a tissue structure of interest in the X-ray image comprises the computer aided detection algorithm being adapted to evaluate the X-ray image for tissue structure shape and compare the tissue structure shape with a plurality of pre-determined tissue structure shapes and wherein the computer aided detection algorithm is adapted to evaluate spectral information of the X-ray image for detecting the tissue structure of interest.
