Development and advancement in X-ray technology
In 1895, a groundbreaking discovery was made by German physicist Wilhelm Roentgen - the X-ray. This new form of radiation was first demonstrated when he took the first X-ray image of his wife's hand, revealing her bones and even her wedding ring with striking clarity [1].
Since its inception, X-ray technology has evolved significantly, becoming the oldest and most common medical imaging method [2]. Here, we delve into some of the major developments that have shaped the field of medical imaging.
Shortly after X-rays began to be used medically, artificial contrast agents like barium sulfate were developed to enhance imaging of the alimentary tract. Later, contrast media that could be injected into blood vessels allowed visualization of arteries, veins, and the urinary tract, expanding the diagnostic capabilities of X-rays beyond just skeletal imaging [1].
During and after World War I, X-rays were extensively used to diagnose fractures and locate foreign bodies such as bullets, establishing X-rays as a critical diagnostic tool in medicine [1].
In 1971, a revolutionary evolution of X-ray technology was introduced - Computed Tomography (CT) scanning. Unlike conventional X-rays producing only 2D images, CT created detailed cross-sectional 3D images of the body, helping physicians identify physical lesions causing diseases with much greater accuracy [4].
More recent research has focused on developing new materials for X-ray detectors. Modern detectors primarily use rigid inorganic scintillator materials, which limit patient comfort and detector flexibility. Recent advancements have led to the development of a flexible, all-inorganic "metafabric" scintillator, promising wearable, conformal X-ray detection and shielding applications [5].
Beyond traditional X-rays, newer medical imaging modalities have evolved, including various techniques such as computed tomography and others, enhancing diagnostic precision and patient care [2][3].

The evolution of X-ray technology in the medical field has led to significant advancements, such as the use of artificial contrast agents and later, injectable contrast media, which have expanded diagnostic capabilities beyond just skeletal imaging [1]. Additionally, the introduction of Computed Tomography (CT) scanning in 1971 has revolutionized medical imaging by creating detailed 3D images, providing physicians with greater accuracy in identifying physical lesions causing diseases [4].
