Factors affecting image quality for optimal radiodiagnosis

Abstract

The discovery of X-rays and the ability to view, non-invasively, the human body has greatly facilitated the work of professionals in diagnosis of diseases. It is necessary to adopt optimisation strategies to maximise the benefits (image quality) and minimise risk (dose to the patient) in radiological facilities as well as focus on image quality. The implementation of optimisation strategies involves an understanding of images acquisition process and value of the various parameters and their impact in image quality. The objective of this review was to analyse the role of different viewing parameters used in radio diagnosis. The relationship between the quality parameters of digital radiographic images including resolution (spatial resolution and contrast resolution), noise, and artefacts and optimising image quality parameters in regard to radiation dose is a challenge. Therefore each evaluation method should be utilised and employed according to its aptitudes to improve image quality and imaging process.
