The initial flow field of an impulsively started incompressible viscous flow over an elliptic cylinder is analyzed by the method of matched asymptotic expansions. Analytical solutions for the outer and inner flow fields are obtained to the third orde

Direct digital mammography (DDM) is currently undergoing clinical trial in the United States. The likely outcome of the current clinical trials is that DDM will be found to have appropriate diagnostic accuracy for clinical use for both screening and

Storage phosphor imaging is one of the first clinically applied technologies for full breast digital mammography and is a potential new method for screening and diagnostic mammography [1],[2]. In this study, we compared how well radiologists were abl

A recently completed ROC study of digital mammography using a 100 micron pixel storage phosphor receptor showed that digital mammography and conventional screen film mammography were essentially equivalent in areas under the ROC curve. In this study,

The sensitivity of mammography for the detection of breast cancer is decreased in the radiodense breast. Storage phosphor digital radiographic systems have a wider latitude of exposure than conventional mammographic screen film systems. By using low

We are examining the feasibility of performing digital mammography by combining a storage- phosphor image receptor with a highly efficient x-ray system. The image receptor consists of Fuji series HR-V high resolution imaging plates and a Fuji 9000 re

The purpose of this work is to examine the feasibility of dual-energy techniques to enhance the detection of microcalcifications in digital mammography. The digital mammography system used in this study consists of two different mammography systems;

Microcalcifications can be identified on mammograms in approximately 50 - 55% of breast cancer cases. Three factors affect the ability to use the presence of microcalcifications as a sign of cancer. They must be seen (conspicuity), their shape must b

Projection radiography, based on the storage phosphor (SP) imaging medium is a promising but challenging technology. SP plates consist of phosphor particles that are embedded in a polymer binder like film and then coated onto a flexible backing. Imag

Improvements in mammography equipment related to a decrease in pixel size of digital mammography detectors raise questions of the possible effects of these new detectors. Mathematical modeling suggested that the benefits of moving from 100 to 50 micr
