A CT scan (Computed Tomography) is a non-destructive inspection process that captures X-ray projection data from multiple angles to reconstruct cross-sectional or 3D volumetric images.
There are two primary scanning configurations:
- Industrial CT: The object typically rotates on a turntable while the X-ray source and detector remain stationary. This method is optimized for high-resolution inspection of components and materials.
- Medical CT: The X-ray source and detector rotate around a stationary subject (gantry system).
In both approaches, the collected data is processed by software to visualize internal structures without damaging the object.
