Magnification views are a common way to perform a secondary examination when
suspicious abnormalities are found in a screening mammogram. The visibility of …

Dosimetric studies in mammography are addressed by means of a Monte Carlo simulation
program. The core of this program (DOSIS: dosimetry simulation studies) is a simulation …

Magnification, which is considered to be a relatively high" dose cost" mammographic
technique, is a complementary examination performed on women exhibiting breast …

Purpose: The purpose of this study was to compare and validate three methods to simulate
radiographic image detectors with the Monte Carlo software mcnp/mcnpx in a time efficient …

In routine applications, information about the photon flux of x‐ray tubes is obtained from
exposure measurements and cataloged spectra. This approach relies mainly on the …

Mammography is the technique with the highest sensitivity and specificity, for the early
detection of nonpalpable lesions associated with breast cancer. As screening …

A mathematical model, based on Monte Carlo simulation, is proposed for deriving absorbed
