The purpose of the present work was to compare the quality of low-dose projections from a photon-counting with a flat-panel system, and to evaluate a novel image processing method. Images were acquired of phantoms in both systems at average glandular

The purpose was to estimate the effective dose of Toshiba/Canon thorax localizer radiographs for available parameter settings, and to test their dose modulation ability. Localizer radiographs were acquired of anthropomorphic chest phantoms (body mass

Our aim was to examine the impact of different arm positions during imaging of the localizer radiograph(s) on effective dose for exposure-controlled computed tomography (CT) (Siemens/Canon) scans of the neck to pelvis. An anthropomorphic whole-body p

We examined interpretive efficiency and variability in true- and false-positive detection (TP, FP) for radiologists screen-reading with digital breast tomosynthesis as adjunct to full-field digital mammography (2D/3D) relative to 2D alone in populati

Clinical studies using different imaging protocols to perform digital breast tomosynthesis (DBT) were reviewed (2008-14) to assess interpretive accuracy. Descriptive pooled statistics were used to estimate and summarise accuracy measures for each typ
