The present invention relates to device and method for correction of a medical breast image. To provide for an improved correction, said device comprises a medical image input (31) for obtaining a medical breast image of subject's breast potentially showing artificial deformations of the breast, a scan image input (32) for obtaining a scan image of the same subject's breast showing the breast in a predetermined position of the subject and comprising surface information of the breast, a simulation unit (33) for generating a simulated medical breast image from the obtained medical breast image, said simulated medical breast image showing the breast in the same predetermined position of the subject as the scan image and representing the breast surface by a surface mesh, wherein said simulation unit (33) is configured to generate said simulated medical breast image based on a volumetric biomechanical model, and wherein material parameters of the biomechanical model are varied for aligning the biomechanical model with the breast surface extracted from the scan image, and a correction unit (34) for determining corrections for correcting the simulated medical breast image for said artificial deformations by use of the scan image by applying a surface matching between said surface mesh and said scan image and for applying the determined corrections to the obtained medical breast image to obtain a corrected medical breast image.
