A mammography apparatus has at least one x-ray source to emit x-ray radiation and an x-ray detector with a number of pixels. The mammography apparatus is designed so that the x-ray radiation is emitted into the breast tissue of a patient at a number of positions, and the x-ray radiation is detected by the x-ray detector after it has passed through the breast tissue. The positions have different distances from the shoulder-to-shoulder axis of the patient.
