title: Dose reduction in mammography.
abstract: Two mammographic imaging systems (Xerox and Kodak Min-R) were evaluated. Three hundred consecutive mammographic examinations were performed utilizing both imaging systems. Results of these studies indicated equivalency of image detail at identical source-to-image receptor distance (SID). Patient exposure as measured by the thermoluminescent dose meter for Kodak Min-R system was approximately 25% that of Xeromammography system. Due to reduced power requirement, it is possible to increase the SID when Min-R system is employed for imaging. Improved geometric arrangement provided superior diagnostic images in 5.5% of 200 comparison cases.
