TLDR
An image simulation chain has been devised from which various doses and other generic system parameters can be simulated, and preliminary results show that the method provides a good quality initial simulation of real CDMAM images.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.read more

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).

Operation method for proofreading manuscript by using computer
TL;DR: In this article, an operation method for proofreading a manuscript by using a computer is presented. But the method does not require manual proofreading in word-for-word mode, is high in automation, can effectively improve stability and accuracy of manuscript proofreading, can be wide in application range, reduces working intensity of the proofreading staff, and can not affect human health.

Accuracy of a simple method for deriving the presampled modulation transfer function of a digital radiographic system from an edge image.
TL;DR: A simple variant of the edge method that produces sufficiently accurate MTF values for frequencies up to the Nyquist frequency limit of the detector with little effort in edge alignment and computation is reported on.

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.

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
Bénédicte Grosjean,Serge Muller +1 more
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.
