This book serves as an essential and comprehensive guide to Cone Beam Computed Tomography (CBCT), a cutting-edge imaging technology that has revolutionized diagnostics in both dentistry and medicine. With an in-depth exploration of the underlying principles of CBCT, this resource covers the fundamental physics that drive this imaging technique. The reader will gain a thorough understanding of how CBCT works, including its ability to generate high-resolution 3D images from multiple X-ray projections, which enables precise visualization of structures not visible through conventional 2D radiography. This technical foundation sets the stage for a deeper appreciation of how CBCT contributes to various fields.
