Device, imaging system and method for correction of a medical breast image

A method comprising:

• obtaining a medical breast image of a subject's breast potentially showing artificial deformations of the breast,
• obtaining a scan image of the subject's breast showing the breast in a predetermined position of the subject and comprising surface information of the breast,
• generating a simulated medical breast image from the obtained medical breast image, the 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 the simulated medical breast image is generated 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,
• determining corrections for correcting the simulated medical breast image for the artificial deformations based on the scan image by applying a surface matching between the surface mesh and the scan image,
• applying the determined corrections to the obtained medical breast image to obtain a corrected medical breast image, and
• displaying the corrected medical breast image.

A non-transitory computer-readable medium that includes a program that, when executed by a processing system, causes the processing system to:

• obtain a medical breast image of a subject's breast potentially showing artificial deformations of the breast,
• obtain a scan image of the subject's breast showing the breast in a predetermined position of the subject and comprising surface information of the breast,
• generate a simulated medical breast image from the obtained medical breast image, the 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 the simulated medical breast image is generated 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,
• determine corrections for correcting the simulated medical breast image for the artificial deformations based on the scan image by applying a surface matching between the surface mesh and the scan image,
• apply the determined corrections to the obtained medical breast image to obtain a corrected medical breast image, and
• display the corrected medical breast image.
