INTRODUCTION

1.1 Background of the Study

Radiography, a technique utilizing X-rays to view the internal structure of an object, plays a pivotal role in various modern industries, including healthcare, manufacturing, and materials science. This technology, which began with Wilhelm Conrad Roentgen’s discovery in 1895, has evolved substantially over the decades, advancing from simple film-based systems to sophisticated digital imaging modalities. Modern radiography encompasses various techniques such as computed radiography (CR), digital radiography (DR), and fluoroscopy, each offering distinct advantages in imaging resolution, speed, and diagnostic capability (Buls et al., 2021).

In the healthcare sector, radiography is integral to diagnosing and monitoring diseases, ranging from broken bones to complex internal conditions. The development of digital radiography has significantly enhanced diagnostic accuracy and efficiency. Unlike traditional film-based systems, digital radiography provides immediate image acquisition and allows for advanced image processing techniques, which improve diagnostic outcomes and patient management (Sirdhar et al., 2020).

In industrial applications, radiography is crucial for inspecting the integrity of materials and structures. Non-destructive testing (NDT) methods, including industrial radiography, are employed to ensure the safety and reliability of critical components in aerospace, automotive, and construction industries. The use of radiographic testing in these sectors helps detect internal flaws and assess material properties without damaging the components, thus preventing costly failures and ensuring compliance with safety standards (Schick et al., 2022).

The evolution of radiography technologies has led to significant advancements in image quality and diagnostic capabilities. The introduction of digital radiography and advancements in image processing algorithms have enhanced the precision of radiographic examinations. These technologies allow for better visualization of subtle abnormalities and detailed anatomical structures, which are essential for accurate diagnosis and effective treatment planning (Hodgkin et al., 2021).

Additionally, radiography plays a critical role in materials science and engineering, where it is used to investigate the internal structure of samples and products. This application is particularly important in the development and quality control of new materials, such as composites and advanced alloys. Radiographic techniques enable researchers to analyze internal features, such as voids and inclusions, which can significantly impact the material's performance and longevity (Choi et al., 2019).

Despite its many benefits, the use of radiography also presents challenges, including radiation exposure and the need for specialized training. Advances in technology have reduced radiation doses and improved safety protocols, but continuous research and development are necessary to address these concerns and optimize radiographic practices (Moss et al., 2023).

In summary, radiography remains a cornerstone of modern industry, offering critical insights into the internal structures of both biological and material samples. Its continued evolution promises further enhancements in diagnostic capabilities and industrial applications, making it an area of significant interest for ongoing research and development.
