Scatter radiation intensities around full-field digital mammography units

A comparison of calibration data from full field digital mammography units for breast density measurements

BACKGROUND Breast density is a significant breast cancer risk factor measured from mammograms. The most appropriate method for measuring breast density for risk applications is still under investigation. Calibration standardizes mammograms to account for acquisition technique differences prior to making breast density measurements. We evaluated whether a calibration methodology developed for an...

X-ray scattering in full-field digital mammography.

Effects of x-ray scattering on full-field digital mammography are analyzed with the scattering model of Seibert and Boone [Med. Phys. 15, 567-575 (1988)]. A new method is introduced for the estimation of model parameters from measurements. It is shown that with breasts thinner than a certain threshold, removing the anti-scatter grid leads to an improved contrast-to-noise ratio with a smaller pa...

Realizing the Benefits of Full-Field Digital Mammography

Full Field Digital Mammography with Breast Cushions in Screening Subjects

To explore the impact of radiolucent breast cushions on breast pain and image quality of full field digital mammography (FFDM) in screening subjects. The American College of Radiology (ACR) phantom and fifty-four women were enrolled in this study. Use of cushions reduced pain (p < 0.001). The imaging quality with cushions was inferior to those without cushions in phantom studies (p ≦ 0.01), on ...
