Abstract
Cone Beam Computed Tomography (CBCT) has emerged as a pivotal imaging modality across various disciplines, providing three-dimensional visualisation with significant applications in dentistry, medical diagnostics, and industrial fields. This article presents a comprehensive overview of key aspects in CBCT imaging, encompassing the critical topics of Field of View (FOV), Resolution, Dose Considerations, and Artefacts. The Field of View (FOV) is a fundamental parameter influencing the scope and application of CBCT. This article explores the impact of different FOV settings on image acquisition, highlighting considerations for selecting an optimal FOV based on the specific diagnostic requirements of diverse clinical scenarios. Resolution plays a pivotal role in defining the clarity and precision of CBCT images. The article delves into the nuances of spatial and contrast resolution in CBCT, addressing the technological advancements and challenges associated with achieving high-resolution imaging while minimizing radiation exposure. Dose considerations are paramount in any medical imaging technique, and CBCT is no exception. This article provides an analysis of radiation dose management strategies in CBCT, emphasizing the importance of balancing diagnostic efficacy with patient safety. It explores dose optimization techniques, dose monitoring, and advancements in technology aimed at minimizing radiation exposure. Artefacts are inherent challenges in CBCT imaging that can compromise diagnostic accuracy. Understanding artefacts is crucial for practitioners to enhance the reliability and interpretability of CBCT images.
