Introduction

X-ray imaging has played a pivotal role in modern science and medicine since its serendipitous discovery by Wilhelm Conrad Roentgen in 1895. The ability to non-invasively penetrate opaque materials and visualize internal structures has revolutionized various fields, making X-ray technology an essential tool in medical diagnostics and non-destructive testing (NDT) applications [1]. Over the past century, X-ray imaging has undergone remarkable advancements, leading to the development of diverse imaging techniques and applications that continue to shape our understanding of the world around us. This research article presents a comprehensive review of X-ray imaging techniques and their wide-ranging applications, highlighting their profound impact on both scientific research and medical practices [2]. Starting with an exploration of the fundamental principles of X-ray imaging, we delve into the intricacies of X-ray generation, interactions with matter, and the formation of X-ray images. Understanding these fundamental principles is essential to grasp the complexities of the various imaging modalities discussed throughout this article [3]. In the medical field, X-ray imaging has become an indispensable tool for diagnosing various conditions and guiding medical interventions. From the early days of radiography to the more sophisticated computed tomography (CT) and interventional procedures, X-rays have paved the way for improved patient care and treatment outcomes [4]. We will explore the current state of medical X-ray imaging, as well as the advancements in image processing techniques and dose reduction strategies that have improved both diagnostic accuracy and patient safety. Beyond medicine, X-ray imaging finds extensive applications in diverse industries and scientific research [5]. In material science and engineering, X-ray analysis enables non-destructive testing, allowing researchers to examine the internal structures of materials without compromising their integrity. Furthermore, security screening applications benefit from X-ray imaging's capability to detect hidden contraband and hazardous materials, safeguarding public safety [6]. As technology continues to advance, so does the potential of X-ray imaging. Emerging trends in the field, such as phase-contrast X-ray imaging, dual-energy imaging, and spectral CT, offer exciting prospects for enhanced imaging capabilities and novel applications. Additionally, the integration of artificial intelligence and machine learning algorithms with X-ray image analysis opens up new avenues for automation, accelerated diagnostics, and improved decisionmaking [7]. However, despite its numerous advantages, X-ray imaging also faces challenges that researchers strive to overcome. Concerns about ionizing radiation dose, image artifacts, and the need for improved soft tissue contrast in X-ray images persist. This article will discuss these challenges and present potential research directions to address them effectively [8]. X-ray imaging techniques have undergone a remarkable evolution, positioning themselves at the forefront of medical diagnostics, material analysis, and security applications [9]. As we continue to unravel the full potential of X-ray technology, this comprehensive review aims to shed light on the diverse applications and future prospects, underscoring the invaluable role X-ray imaging plays in advancing scientific knowledge and improving the quality of human life [10].
