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

: The X-ray source and electronic detector array rotate around the patient to take measurements from many angles. 2. Image Formation & Reconstruction

The raw data gathered by detectors is converted into visual slices through mathematical processes: Download TomodensitomГ©trie principes pdf

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

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

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

: A scale used to quantify tissue density, where water is 0 HU and air is -1,000 HU. 3. Technological Evolutions Image Formation & Reconstruction The raw data gathered

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