Abstract
With the recent developments in digital mammography, it is becoming increasingly important to be able to compare different technologies used for detecting breast cancer. By using simulation tools, it may be made possible to not only compare the images generated by different technologies but also the effect of dose levels and other imaging parameters within the same system. Images of a test phantom (CDMAM) have been simulated in this study as a proof of principle. An image simulation chain has been devised from which various doses and other generic system parameters can be simulated. Preliminary results show that the method provides a good quality initial simulation of real CDMAM images.

Evaluation of Digital X-Ray Detectors for Medical Imaging Applications

TL;DR: In this paper, the authors evaluated the performance of two CMOS active pixel sensors (APS) in terms of the photon transfer curve (PTC), the modulation transfer function (MTF), the normalized noise power spectrum (NNPS), and the resultant detective quantum efficiency (DQE).

Method of simulating dose reduction for digital radiographic systems

TL;DR: The aim of the present work was to develop a method of simulating dose reduction for digital radiographic systems that can be used to modify an image collected at one dose level so that it simulates an image of the same object collected at any lower dose level.

Quantification of Al-equivalent thickness of just visible microcalcifications in full field digital mammograms.

TL;DR: A more direct measure of the threshold contrast-detail characteristics of microcalcifications in clinical mammograms is proposed, which also takes into account routine processing and display and indicates that it may be possible to quantify the performance of a digital mammography detector including processing and viewing for the detection of microCalcifications.

Impact of textured background on scoring of simulated CDMAM phantom

TL;DR: The impact of structured background on this performance assessment, using simulated CDMAM phantom images with flat and textured backgrounds, shows that detectability performance in textured background is even more degraded and is not as dose dependent as it is in flat backgrounds.
