Digital radiographic system – a literature review

Abstract

The transition from conventional to digital radiographic systems has transformed the diagnostic imaging services in both human and veterinary medicine in the last 20 years. The introduction of direct and indirect digital radiographic systems in the routine of many hospitals and image laboratories has turned the use of post-processing tools more frequent and important. Thus, the need of knowledge about these resources motivated this literature review, which aims to contribute in a simple way to the understanding of the physics involved in the acquisition of computerized radiographic images. Additionally, we hereby present the research evolution to validade the use of digital images for thoracic evaluation and the contribution of post-processing to clinical applications and diagnosis.
