Abstract

This article reports on recent research findings into the factors that govern and influence the detectability performance of different types of digital radiography including computed radiography (CR) and direct digital radiography (DR). Low contrast-detail analysis method is proved to be an appropriate evaluation method to optimise image quality and to examine the potential of radiation dose reduction of CR and DR. Additionally; this method is helpful to understand how the different factors influence image quality. Low contrast-detail evaluation method is based on the detectability performance of the imaging systems. There are different factors that influence the detectability performance. The influences level of these factors on detectability performance of different systems is not exactly same. These factors and their influences on different digital radiography systems are discussed in this article. While some of these factors are inherited by the system itself such as detector properties and utilised technology of image processing, factors such as exposure factors should be deeply understood and effectively adjusted by radiographers to optimize optimise system detectability performance and hence the image quality.
