Assessment Of Radiation Dose In Digital Radiography System -A Review Article

Background: The evaluation of patient doses has gotten more attention, but it's still a concern due to computerized technologies (Digital). Compared to a traditional screen-film system, the advancement of digital technology allows for a 50% reduction in radiation exposure without sacrificing image quality. Digital system provides similar or better diagnostic performance and several additional benefits, but there is a risk of overexposure without a negative impact on image quality. Digital radiographic imaging technologies are appropriate for various clinical applications and may produce satisfactory image quality across a wide exposure limit. Over radiation might result in increased dose levels without improving image quality; as a result, experimental data analysis is a continuous process that can provide information on radiation exposure appropriateness. Digital systems, on the other hand, stand out for their adaptability: the acquisition dose may be changed without compromising image quality, as well as vice versa. The imaging settings should be fine-tuned to achievethe optimum results from a given system. Traditional methods of dose containment, including placement and collimation, apply equally well to digital and traditional processes. Dose reduction is becoming increasingly possible because of digital technology. Simultaneously, there is a danger of drastically increasing the patient's dose without realizing it because of a lack of visual control. As a result, digital radiography requires dosage indicators and dose monitoring. A step closer to contemporary radiation protection is the adoption of picture quality classes based on the dose needs of specific clinical indications; manufacturers have made numerous enhancements to digital radiography equipment due to the detector and technological advancements. Because of digital imaging techniques, x-rays can now be storeddigitally and used at any time by altering contrast to the viewer's preference. This technique hasensured that no radiographs are lost and enables digital distribution throughout hospitals via web-based technologies.
