ABSTRACT:
A mammography apparatus and method having an X-ray tube, an image receiver, the image receiver having one edge in contact with a patient, a compression paddle between the tube and the receiver, able to be moved up and down parallel to a direction of propagation of the X-rays, means for keeping the compression paddle in position in the radiation propagation direction, the compression paddle, in its compression position, being movable in at least one direction perpendicular to the direction of X-ray propagation and parallel to the contact edge of the image receiver. This allows a patient's breast to be rolled and presented to the image receiver in different positions thereby reducing ambiguities in possible detection of a lesion due to layers of tissue overlapping when images are taken.
