摘要：
A method and apparatus for the improved display of digital mammographic images, which were measured in the context of a mammographic imaging system and displayed on a workstation monitor. The mammogram consists of a plurality of pixels with each pixel having a pixel value assigned thereto. The pixel values of all pixels of the mammogram lie within a pre-determined first range of values and the pixel values of pixels of a subsection of the mammogram lie within a second range of values, which represents a subset of the first range of values. A mammogram having a subsection with increased contrast, such that the second range of pixel values of the pixels in the subsection are spread by a spreading function, whereby the amount of the spreading function changes over the subsection. In this way, an improved display is created, by means of those representations of the mammogram regarding their contrast in subsections being optimized, at the same time the representation for a user is improved without artifacts.
