Abstract
Computed radiography (CR) systems are used to perform radiographic examinations. CR systems possess various advantages over conventional radiography and are recognized globally. CR systems are facing strong competition with the introduction of more advanced and completely digital, direct digital radiography (DDR) systems. Both the modalities have some or the other advantages over each other. Still, direct digital radiography (DDR) systems is increasingly gaining the popularity and probably will take-over the CR systems in near-future. The common disadvantage with these modalities is an artifact Artifacts may occur on both the CR and the DR images and can degrade or mimic the clinical features. Several factors affect the image quality and contribute to the formation of artifacts. To optimize the image quality, it is important to understand the cause of artifacts and how they can be prevented. Despite the latest advancements in digital imaging, quality assurance and proper exposure technique is still a crucial challenge in radiography. The aim of this paper is to discuss and review the computed radiography and its artifacts to comprehend and understand the same for a better qualitative radiographic results.
