14. An arrangement (800) for detecting a Region of Interest in an image data set, especially digitalized X-ray image, which arrangement extracts phase information from said image, uses said phase information for differentiating between different lines and edges, and skews said lines towards a centre, the arrangement comprising:
- a processing unit (801), a module (802) for obtaining image masks, a sampling module (803), a calculating module (804), filtration module (805), a classification module (806) and a support vector machine and/or artificial neural network module (807).
