Role of Radiographers in Computed Tomography: Image Quality Optimization, Radiation Dose Reduction, and Patient Safety

Abstract

Computed tomography (CT) is a widely utilized diagnostic imaging modality that provides high-resolution cross-sectional visualization of anatomical structures. Radiographers play a critical role in optimizing image quality while ensuring radiation safety. This review aims to evaluate the role of radiographers in CT imaging, with particular emphasis on image quality optimization, radiation dose reduction, and patient safety. The review is based on an analysis of published literature and clinical practices. Key techniques, including automatic exposure control (AEC), iterative reconstruction (IR), and adherence to the ALARA (As Low as Reasonably Achievable) principle, are discussed. Additionally, patient preparation, contrast administration, and emerging technologies such as artificial intelligence are explored. Radiographers are essential in balancing diagnostic accuracy with radiation protection, thereby contributing significantly to safe and effective imaging practices.
