Apparatus and method for the computer-assisted analysis of mammograms

摘要

Device for the computer-assisted analysis of digital mammograms, with a means for detecting a contour line (k, k1, k2, k3, k4), which is at a defined by an object the object region (20) of a mammogram (2, 2a, 2b, 2c, 2d) in the manner of a cover, wherein the means for detection of the contour line (k, k1, k2, k3, k4) as a function of the image characteristic of said mammogram (2, 2a, 2b, 2c, 2d) a threshold value method and / or a scan lines method uses,wherein as a function of the image characteristic of the material to be processed mammogram (2, 2a, 2b, 2c, 2d)– a threshold value method, in which at least one threshold value (b, b1) for binarizing said mammogram (2, 2a, 2b, 2c, 2d) is used, and / or– a scan lines of the process, in which the gradient of the said mammogram (2, 2a, 2b, 2c, 2d) along different scan lines (r) is determined,for the detection of a one object region (20) that borders the contour line (k) of said mammogram (2, 2a, 2b, 2c, 2d) is used, wherein with the aid of said mammogram (2, 2a, 2b,..
