Linear scanning sensors for medical X-ray imaging

8 The advantages of digital radiography (DR) over screen-fi lm (SF) techniques in medical X-ray imaging are well documented in the literature and unanimously acknowledged by radiologists as well as physicists. For the past decade manufacturers have developed a number of commercial digital X-ray imaging systems covering the full range of radiographic applications. The tight requirements in terms of image quality and X-ray dose have made mammography one of the last medical X-ray imaging examinations to date to fall under the pressure of the “digital revolution”. This is confi rmed by the recent approval by the US Food and Drug Administration of a number of full-fi eld digital mammography (DM) systems for clinical use .
