5.6 COMPRESSION SYSTEM
Good mammographic image quality requires sufficient compression of
the breast. The breast is compressed against the cassette holder with the
compression paddle, which is either manually moved using the manual
compression wheel or motor-driven using the foot pedals.
5.6.1 Paddles
A compression paddle consists of an acrylic compression plate and a
metal supporting frame with fixings used to attach the paddle to
Diamond’s compression paddle arm. Graphics indicating the AutoPoint
AEC detector locations are silk screen printed onto the acrylic part of each
paddle to the extent the size of the paddle acrylic allows. Paddles are
attached with a straight horizontal movement and removed by first
pressing either one of the compression paddle release keys (7) and then
pulling the paddle out with a horizontal movement.

The surfaces between the compression paddle/arm and the cassette
holder are smooth to enable safe, comfortable positioning by the
radiographer/technologist.
