The raw data gathered by detectors is converted into visual slices through mathematical processes: This report summarizes the fundamental principles of (TDM),

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

: A scale used to quantify tissue density, where water is 0 HU and air is -1,000 HU. 3. Technological Evolutions

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