Journal ArticleDOI
Detective quantum efficiency dependence on x-ray energy weighting in mammography
TL;DR: An evaluation of the dependence of detective quantum efficiency on the incident energy spectrum has been made for mammography and it is shown that the optimal weight factors to combine the data in the case the energy is measured are very well approximated if the weight factors are proportional to E(-3).
Journal ArticleDOI
Energy resolution of a photon-counting silicon strip detector
TL;DR: In this article, a photon-counting silicon strip detector with two energy thresholds was investigated for spectral X-ray imaging in a mammography system, and preliminary studies already indicate clinical benefit of the detector.
Journal ArticleDOI
Physical characterization of a scanning photon counting digital mammography system based on Si-strip detectors.
TL;DR: The physical performance of a scanning multislit full field digital mammography system was determined using basic image quality parameters and the detective quantum efficiency (DQE) was found to be independent of the dose level to the detector in the 7-206 microGy range.
Journal ArticleDOI
Scatter rejection in multislit digital mammography
TL;DR: The scatter to primary ratio (SPR) was measured on a scanning multislit full-field digital mammography system for different thickness of breast equivalent material and different tube voltages by using the scatter detective quantum efficiency.
Journal ArticleDOI
Contrast-enhanced spectral mammography with a photon-counting detector
TL;DR: In this article, Spectral imaging is a method in medical x-ray imaging to extract information about the object constituents by the material-specific energy dependence of xray attenuation.
