Optimization of exposure parameters in full field digital mammography

Dose Reduction in Automatic Optimization Parameter of Full Field Digital Mammography: Breast Phantom Study

PURPOSE We evaluated the impact of three automatic optimization of parameters (AOP) modes of digital mammography on the dose and image quality. METHODS Computerized Imaging Reference Systems phantoms were used. A total of 12 phantoms with different thickness and glandularity were imaged. We analyzed the average glandular dose (AGD) and entrance surface exposure (ESE) of 12 phantoms imaged by ...

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 ...

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...
