Computed tomography (CT) is a non-destructive imaging technique that uses a computer to generate cross-sectional images from a series of X-ray projections acquired at multiple angles. This method enables the visualization of internal structures and defects without disassembling the object. Scanning methods are typically categorized by their X-ray beam geometry, such as parallel beam, fan beam, and cone beam systems. The computer processes the acquired data to reconstruct cross-sectional images (tomograms) or 3D models, utilizing mathematical principles such as the Radon transform.
