This pioneering work brings together recommendations sanctioned by the International
Commission on Radiological Protection (ICRP) and documents 40 years of cutting-edge …

Previous work [Burgess et al., Med. Phys. 28, 419–437 (2001)] has shown that anatomical
noise in projection mammography results in a power spectrum well modeled over a range of …

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 …

We examine the noise advantages of having a computed tomography (CT) detector whose
spatial resolution is significantly better (eg a factor of 2) than needed for a desired resolution …

Purpose: To investigate the correlation and stationarity of noise in volumetric computed
tomography (CT) using the local discrete noise‐power spectrum (NPS) and off‐diagonal …

In recent years, there has been an increasing interest in exploring the feasibility of dedicated
computed tomography (CT) breast imaging using a flat‐panel digital detector in a truncated …

Purpose In this work, the effect of noise on the precision in the modulation transfer function
(MTF) calculation using different phantoms is investigated. Three different techniques are …

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 …

Model observers have been developed which incorporate a specific imaging task, system
performance, and human observer characteristics and can potentially overcome some of the …

Purpose: Quality assurance in computed tomography (CT) is commonly performed with the
Fourier‐based modulation transfer function (MTF) and the noise variance, while more …
