Popis:	Mammography is now established as a relatively routine method of examination of the breasts. Although it is not yet accepted as a screening procedure for breast cancer there is evidence that it could play a role in early detection and salvage of life if applied on a wide enough scale (1–3). Because of the problems inherent in the routine viewing of large numbers of examinations of presumably asymptomatic patients we have proposed the automation of reading of the radiographs by means of optical scanning and computer interpretation. Our work has, we believe, demonstrated the feasibility of this method. Films of the breasts were made, using bolus immersion technic. The breast was immersed in either mineral oil or alcohol, and translateral decubitus films were obtained. The resulting radiograph was converted to a positive image and scanned by a converted radio-facsimile scanner. This scanner carries the print on a rotating drum and advances the photocell by means of a lead-screw to measure the reflected light...
