A flexible, durable, sanitary, adhesive-backed sheet is applied to the skin-contacting surfaces of a mammography bucky prior to commencing a mammography procedure, and is removed from the bucky once the procedure is complete, without leaving a residue behind. The sheet is made of a non-woven polymeric material that gives the sheet a fabric-like or cloth feel, and is substantially incompressible in response to forces applied during a mammography procedure. The sheet insulates the patient from the temperature differential between the patient's skin and the bucky surfaces. Additionally, the surface of the sheet is embossed with a texture, markings or raised features to enhance the fabric-like feel.
