Benchmarking the performance of fixed-image receptor digital radiography systems. Part 2: system performance metric.

This is part two of a two-part study in benchmarking system performance of fixed digital radiographic systems. The study compares the system performance of seven fixed digital radiography systems based on quantitative metrics like modulation transfer function (sMTF), normalised noise power spectrum (sNNPS), detective quantum efficiency (sDQE) and entrance surface air kerma (ESAK). It was found that the most efficient image receptors (greatest sDQE) were not necessarily operating at the lowest ESAK.

Benchmarking the performance of fixed-image receptor digital radiographic systems part 1: a novel method for image quality analysis.

This is the first part of a two-part study in benchmarking the performance of fixed digital radiographic general X-ray systems. This paper concentrates on reporting findings related to quantitative analysis techniques used to establish comparative image quality metrics. A systematic technical comparison of the evaluated systems is presented in part two of this study.

Diagnostic reference levels for mammography in BreastScreen Queensland.

Diagnostic reference levels assist in the optimisation of radiation exposure parameters within a medical imaging facility. As no Australian DRLs currently exist, radiation doses from mammography in BreastScreen Queensland are analysed. Program-based DRLs of 1.
