Assessment of image quality for digital x-ray mammography systems used in European
screening programs relies mainly on contrast-detail CDMAM phantom scoring and requires …

The purpose of this study was to examine the effects of different resolution and noise levels
on task performance in digital mammography. This study created an image set with images …

Purpose To investigate how various generations of iterative reconstruction (IR) algorithms
impact low-contrast detectability (LCD) in abdominal computed tomography (CT) for different …

Purpose Digital breast tomosynthesis (DBT) is a limited‐angle tomographic breast imaging
modality that can be used for breast cancer screening in conjunction with full‐field digital …

Background Current CT quality control (QC) for low‐contrast detectability relies on visual
inspection and measurement of contrast‐to‐noise ratio (CNR). However, CNR numbers …

Task-based assessments of image quality constitute a rigorous, principled approach to the
evaluation of imaging system performance. To conduct such assessments, it has been …

In conventional industrial computed tomography, the source–detector system rotates in
equiangular steps in-plane relative to the part of investigation. While being by far the most …

Purpose Model observers (MOs) are of interest in the field of medical imaging to assess
image quality. However, before procedures using MOs can be proposed in quality control …

The use of iterative reconstruction (IR) algorithms in CT generally decreases image noise
and enables dose reduction. However, the amount of dose reduction possible using IR …

Evaluation of flat-panel angiography equipment through conventional image quality metrics
is limited by the scope of standard spatial-domain image quality metric (s), such as contrast …
