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

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

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

The raw data gathered by detectors is converted into visual slices through mathematical processes:

) governs the intensity variation of the beam based on the material's linear attenuation coefficient ( Image Formation & Reconstruction The raw data gathered

: The scanner measures how much an X-ray beam is attenuated (weakened) as it passes through different tissues. Beer-Lambert Law : This physical law (

: The geometric principle used to reconstruct a 2D object from its measured projections. formation de l'image - Slideshare
