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 throug...

Digital breast tomosynthesis promises solutions to many of the problems currently associated with projection mammography, including elimination of artifactual densities from the superposition of normal tissues and increasing the conspicuity of true lesions that would otherwise be masked by superimposed normal tissue. We have investigated the performance of a novel tomosynthesis system in a clin...

the use of mammography film-screen is limited in general radiography. the purpose of this study was to compare the effectiveness of mammographic film-screen and standard film-screen systems in the detection of small bone fractures. radiographs were taken from patients' extremities and neck areas using mammography film-screen and standard film-screen (n=57 each). fourteen other radiographs were ...

Soft Copy Digital Mammography creen-film mammography (SFM) has been the standard method used for breast cancer screening and making a clinical diagnosis. It is a valuable modality for the detection and differentiation of breast calcifications. The advantages are the high spatital resolution, the convinient display, and inexpensiveness. However, it has some inherent limitations such as its low d...

the sensitivity and specificity of mammography are limited in highly fibroglandular breasts (acr density c and d). digital mammography provides increased sensitivity in young women and those with moderately dense breasts, and digital three-dimensional mammography (tomosynthesis) promises further improvement. for women with the densest breasts, however, radiography is unlikely to be the optimum ...

Background: Over 90% of mammography machines in Japan have already become digital, however, almost three-fourths of them utilize computed radiography (CR). The majority of them necessitate hard copy diagnosis. Therefore, reliability of soft-copy interpretation of CR mammography is still controversial. The purpose of this study is to assess the usefulness and problems of soft-copy interpretation...

Purpose To investigate the impact of radiation dose on breast density estimation in digital mammography. Materials and Methods With institutional review board approval and Health Insurance Portability and Accountability Act compliance under waiver of consent, a cohort of women from the American College of Radiology Imaging Network Pennsylvania 4006 trial was retrospectively analyzed. All patien...

We have devised a mammogram modeling system which greatly simplifies the development of, and can improve the accuracy and consistency of, computer-aided display and analysis algorithms for digital mammography. Our system segments the five major components of a mammogram: background, uncompressed-fat, fat, dense, and muscle. Differences in the amount and distribution of these components account ...

Nowadays many efforts are being focused on design of general systems to manage medical images. Conventional mammography is currently the most efficient technique to detect early breast cancer. Due to special requirements of breast radiography images, integration of digital mammography in PACS is not yet achieved. In this paper, we present a possible solution with a specific miniPACS design to m...
