How does X-ray equipment and radiographic practice for mammography differ to that used in general radiography (e.g. chest radiography)? You should discuss equipment issues (such as the X-ray tube, generator, beam filtration, collimation, image receptors, X-ray tube/image receptor stand) and radiographic technique. For each adaption for mammography, you should describe the difference to general X-ray systems, and explain why and how the adaption provides an advantage for mammographic imaging. Use tables and figure captions
