Digital radiography exposure indices: A review
Digital radiography (DR) technologies have the advantage of a wide dynamic range compared to their film-screen predecessors, however, this poses a potential for increased patient exposure if left unchecked. Manufacturers have developed the exposure index (EI) to counter this, which provides radiographers with feedback on the exposure reaching the detector. As these EIs were manufacturer-specifi...
متن کاملBreakthroughs in Radiography: Computed Radiography
CE Email comments/questions to [email protected], fax 800-556-3288, or log on to www.VetLearn.com Computed radiography (CR) is a digital imaging technology and digital x-ray image management system that has been used in human and veterinary medicine since the 1980s. CR helps eliminate many of the disadvantages of traditional radiography. A storage phosphor plate collects the pattern of x...
متن کاملComputed Radiography in Perspective
Introduction Imagine the excitement accompanying the first realization that noninvasive visualization of bones was possible. German physicist Wilhelm Conrad Roentgen was working in a darkened room on November 8, 1895, experimenting with electrical charges flowing through a vacuum tube, when a piece of paper coated with barium platinum cyanide glowed. Coincidentally, it had been left near a card...
متن کامل[Computerized estimation of a percent glandular tissue composition in computed radiography mammography].
Measurement of a percent glandular tissue composition (%GTC) is important in terms of the estimation of individual patient exposure dose and the prediction of malignancy, and thus a number of reports for estimating %GTC by use of a mammogram have been published. In this study, we propose a method for estimating individual %GTC by use of computed radiography (CR) mammograms. By employing breast-...
متن کاملOptimization of Digital Mammography Resolution Using Magnification Technique in Computed Radiography
Purpose: To determine whether magnified digital mammography using a computed radiography system can produce better spatial resolution by reducing the focus-object distance, and to define the optimal magnification factor when a large x-ray tube focal spot is used for digital mammography using a CR system. Materials and Methods: Digital images obtained using computed radiography of a breast phant...
