The technology has evolved through several "generations" to improve speed and quality: The raw data gathered by detectors is converted
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 geometric principle used to reconstruct a 2D object from its measured projections.
The raw data gathered by detectors is converted into visual slices through mathematical processes:
