Digital mammography systems allow manipulation of fine differences in image contrast by means of image processing algorithms. Different display algorithms have advantages and disadvantages for the specific tasks required in breast imaging-diagnosis and screening. Manual intensity windowing can produce digital mammograms very similar to standard screen-film(More)
Abbreviations: ANOVA ϭ analysis of variance CLAHE ϭ contrast-limited adaptive histogram equalization HIW ϭ histogram-based intensity windowing MIW ϭ manual intensity windowing MMIW ϭ mixture model intensity windowing MUSICA ϭ multiscale image contrast amplification 1 PURPOSE: To determine the preferences of radiologists among eight different image(More)
PURPOSE To compare the speed and accuracy of the interpretations of digital mammograms by radiologists by using printed-film versus soft-copy display. MATERIALS AND METHODS After being trained in interpretation of digital mammograms, eight radiologists interpreted 63 digital mammograms, all with old studies for comparison. All studies were interpreted by(More)
PURPOSE To determine the speed, accuracy, ease of use, and user satisfaction of various electronic data entry platforms for use in the collection of mammography clinical trials data. METHOD AND MATERIALS Four electronic data entry platforms were tested: standalone personal digital assistant (PDA), Tablet PC, digitizer Tablet/PDA Hybrid (DTP Hybrid), and(More)
A fully automatic algorithm is developed for breast arterial calcification extraction in mammograms. This algorithm is implemented in two major steps: a random-walk based tracking step and a compiling and linking step. With given seeds from detected calcification points, the tracking algorithm traverses the vesselness map by exploring the uncertainties of(More)
RATIONALE AND OBJECTIVES To determine the effects of three image-processing algorithms on diagnostic accuracy of digital mammography in comparison with conventional screen-film mammography. MATERIALS AND METHODS A total of 201 cases consisting of nonprocessed soft copy versions of the digital mammograms acquired from GE, Fischer, and Trex digital(More)
As a potential biomarker for women's cardiovascular and chronic kidney diseases, breast arterial calcification (BAC) in mammography has become an emerging research topic in recent years. To provide more objective measurement for vascular structures with calcium depositions in mammography, a new computerized method is introduced in this paper to delineate(More)
This paper is a study of first and second person pronoun development in the spoken language of two young hearing-impaired children. Pronoun development was examined over a period of 11 months, starting at the age of 29 and 28 months, to determine whether the children's acquisition of these pronouns would reflect normal, delayed or deviant patterns of(More)
