: The X-ray source and electronic detector array rotate around the patient to take measurements from many angles. 2. Image Formation & Reconstruction
: A scale used to quantify tissue density, where water is 0 HU and air is -1,000 HU. 3. Technological Evolutions
: The scanner measures how much an X-ray beam is attenuated (weakened) as it passes through different tissues. Beer-Lambert Law : This physical law ( Download TomodensitomГ©trie principes pdf
: The geometric principle used to reconstruct a 2D object from its measured projections.
This report summarizes the fundamental principles of (TDM), also known as CT scanning, as detailed in various academic and professional resources including course materials from Urofrance and the Collège des Enseignants de Radiologie de France (CERF) . 1. Fundamental Principles : The X-ray source and electronic detector array
: 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 ( This report summarizes the fundamental principles of (TDM),
The raw data gathered by detectors is converted into visual slices through mathematical processes:
