The aim of this study was to compare mean glandular dose (MGD) in all full-field digital mammography (FFDM) and screen film mammography (SFM) systems used in a national mammography screening program. MGD from 31 screening units (7 FFDM and 24 SFM), based on an average of 50 women at each screening unit, representing 12 X-ray models (6 FFDM and 6 SFM) from five different manufacturers were calcu...

Breast imaging in the UK is currently undergoing a major change, with the widespread implementation of full-field digital mammography (FFDM) equipment. This article looks at some of the advanced imaging techniques that have become possible following the development of FFDM units. These techniques may prove to be useful additions to standard mammography for some groups of women.

The modulation transfer function (MTF) describes the spatial resolution properties of imaging systems. In this work, the accuracy of our implementation of the edge method for calculating the presampled MTF was examined. Synthetic edge images with known MTF were used as gold standards for determining the robustness of the edge method. These images simulated realistic data from clinical digital m...

Despite uncertainties with the use of digital breast tomosynthesis (DBT), also called 3D mammography, clinical interest is increasing. Some researchers and patient advocacy groups are promoting its ability to improve breast cancer screenings. Preliminary studies suggest that tomosynthesis has increased specificity and sensitivity over 2D digital mammography (DM), and therefore reduced recall an...

Because modern digital detectors can be tuned to be more efficient than screen-film systems, they automatically lower the radiation dose to the patient while maintaining the image quality radiologists crave. Photon-counting, the method used in Sectra's detector, for example, minimizes patient exposure to radiation. In a 2006 analysis, the British National Health Service Breast Screening Program...

one of the most common and important therapeutic tools used by physicians is prescription. the use of digital systems in the health field has many benefits and significant impacts on the health system. one of these systems is digital prescription. in this article, first, we will review the existing infrastructure and work done in this area, and then with a new perspective on health issues, we w...

Breast is a special type of soft tissue that requires dedicated imaging equipment; mammography being the dominant modality. Although it was started as early as 1940’s, it has made rapid advances in the technique during the last quarter of the 20th century, from xeromamography to fast film-screen mammography to digital MR mammography1-4. Today, mammography equipment is an essential part of the r...
