Abstract
A compression device for a mammography unit includes a compression plate positionable in an x-ray field of the mammography unit, and a radiolucent foam pad removably attached to the compression plate that includes an impermeable exposed surface for contacting tissue disposed on the pad within the x-ray field. The pad includes an adhesive layer on the first surface, or a hook and eye fastener for removably attaching the pad to the compression plate. The pad is attached to the compression plate in the x-ray field of the mammography unit, a breast is compressed using the compression plate, a mammogram of the compressed breast is obtained, the pad producing no significant visual artifact on the mammogram, and thereafter the pad is removed.
