The technology has evolved through several "generations" to improve speed and quality:

Tomodensitométrie is a revolutionary radiological method that produces cross-sectional (axial) images of the human body. Unlike traditional 2D radiography, it uses:

: The geometric principle used to reconstruct a 2D object from its measured projections.

: A common algorithm used to solve for attenuation coefficients in each anatomical slice.

) governs the intensity variation of the beam based on the material's linear attenuation coefficient (
