Low-Dose Computed Tomography: Balancing Radiation Risk and Image Quality Through Emerging Technologies

Computed tomography (CT) imaging is an essential tool in modern medical technology, providing comprehensive cross-sectional images that are crucial for diagnosing a wide range of diseases. However, despite its significant benefits, there are concerns regarding the risks associated with radiation exposure, particularly from high-dose CT imaging, which may lead to long-term adverse effects. This study examines the impact of high radiation doses on biological tissues, the cumulative risks associated with repeated exposure, and the implications for vulnerable populations such as pregnant women and pediatric patients. Furthermore, it analyzes recent advancements in low-dose CT technologies, including AI-powered denoising methods, advanced image reconstruction algorithms, and optimized scanning techniques, all of which aim to reduce radiation exposure without compromising image quality. The study also provides valuable insights into enhancing radiation safety while maintaining diagnostic accuracy. By evaluating the effectiveness of low-dose CT systems across various medical applications, it highlights the future potential of low-dose CT imaging technologies.
