Screen-film image receptors have been the standard detector used in conventional mammography. New developments in detector technology and computers are altering the landscape of mammography imaging. Full Field Digital Mammography (FFDM) offers the promise of revolutionizing the practice of mammography through its superior dose and contrast performance. Advanced applications made possible through digital imaging, such as automated computer-aided diagnosis, dualenergy and 3D tomosynthesis are… Expand
Emerging technologies in breast cancer detection.
While screening mammography is recognized as the most effective method for early detection of breast cancer, this modality has limitations that are the driving force behind efforts to refine existingExpand
[Digital breast tomosynthesis : technical principles, current clinical relevance and future perspectives].
Tomosynthesis is a procedure developed from digital mammography for slice examination of breasts which eliminates the effects of overlapping tissue and allows 3D imaging of breasts and dual-energy imaging is of particular importance. Expand
Implementation of a Full Field Digital Mammography
A digital mammography is proposed and the performance of the implemented system is evaluated to assess the specificity and sensitivity of imaging, the early detection of breast cancer is feasible. Expand
Digital Mammography: An Overview
The paper concludes with a discussion of the future applications of DM, such as computer aided detection and diagnosis, digital tomosynthesis and contrast-enhanced DM. Expand
Microcalcification Assessment with Dark-Field Mammography
The results indicate that dark-field imaging of microcalcifications may enhance the diagnostic validity of current microCalcification analysis and reduce the number of invasive procedures. Expand
Towards Optimization of Image Quality as a Function of Breast Thickness in Mammography: An Investigation of the Breast Thickness Compensation Schemes on Analogue and Digital Mammography Units
The results showed that relative image quality for thicker breasts compared with standard breasts varies greatly with unit type, depending on the thickness compensation scheme implemented by the particular AEC system. Expand
Validation of a digital mammographic unit model for an objective and highly automated clinical image quality assessment.
The quantitative results given in this paper show that the images simulated by the X-ray source/digital detector model are useful for image quality assessment in the case of all studied exposure conditions using either human or automated scoring and confirm that with the XRS/DD model the image quality Assessment can be automated and the whole time of the procedure can be drastically reduced.

Computation of realistic virtual phantom images for an objective lesion detectability assessment in digital mammography.
MTF* is a modified MTF taking into account the effects due to X-ray scatter in the breast and magnification, and results obtained with the structural similarity index prove that the simulated images are quite realistic in terms of contrast and noise. Expand
Retrospective Comparison of Contrast-Enhanced Spectral Mammography with Digital Mammography in Assessing Tumor Size in 668 Cases of Breast Cancer
The accuracy of measurement of tumor size using CESM is independent of lesion size, but it overestimates the size by 5 mm on average, but the difference is not dependent on grading, biological subtype of the carcinoma, or patient age. Expand
Contrast-Enhanced Spectral Mammography: Comparison with Conventional Mammography and Histopathology in 152 Women
CESM may provide higher sensitivity for breast cancer detection and greater diagnostic accuracy than conventional mammography and should be considered for use in preoperative women. Expand


X-ray imaging with amorphous selenium: optimal spectra for digital mammography.
The results indicate that use of a kilovoltage setting in the current mammographic range, and a molybdenum target spectrum is appropriate for digital readout of a-Se detectors. Expand
Mammography grid performance.
Differences in grid performance exist, and at 25 and 30 kVp, the cellular grid exhibited superior contrast improvement factor performance, whereas one of the linear grids exhibited superior Bucky factor performance. Expand
