DBT is a three-dimensional (3D) breast imaging technology that uses a rotating X-ray source to acquire multiple image slices at several angles. The X-ray source rotates around the breast in an arc. Serial exposures are taken every few degrees in the arc rotation. These images are then reconstituted by software to produce a 3Dimage of the breast, similar to CAT scanning. It has been suggested th...

In this paper, we present the results of mammography quality control tests related to the work with Portuguese mammography equipment, either in conventional or in digital mammography computed radiography, showing the main differences in the tested equipments. Quality control in mammography is a very special area of quality control in radiology, which demands relatively high knowledge on physics...

This paper on digital mammography image acquisition is 1 of 3 papers written as part of an intersociety effort to establish image quality standards for digital mammography. The information included in this paper is intended to support the development of an ACR guideline on image quality for digital mammography. The topics of the other 2 papers are digital mammography image display and digital m...

Most breast imaging programs have replaced film-screen mammography systems with digital mammography. Other breast imaging methods, such as digital breast tomosynthesis, complement the tools available for screening and diagnosis of breast cancer. This article examines digital mammography, other digital breast imaging modalities, and the effects of these technologies on practice, quality, efficie...
