In digital mammography, imaging acquisition, display and storage processes are separated and individually optimized. Radiation transmitted through the breast is absorbed by an electronic detector with an accurate response over a wide range of intensities. Once these data are stored, they can be displayed by means of computer image-processing techniques to allow arbitrary settings of image brightness, contrast and magnification, without the need for further radiological exposure of the patient. In this article, the current state of the art in technology for digital mammography and clinical trials data supporting the use of this technology are reviewed. In addition, several potentially useful applications, currently under development with digital mammography, are described.
Mammography; Breast cancer; Digital radiography; Full-field digital mammography
