CT Scanner — Working Principle (Interactive)
This interactive CT scanner simulation demonstrates how X-rays rotate around the patient, pass through tissues, attenuate differently, and are detected to reconstruct CT images.

1) X-ray Generation
Electrons strike a tungsten target inside the X-ray tube producing high-energy X-rays.
2) Beam Transmission
The X-ray beam passes through the patient while tissues absorb different amounts of radiation.
3) Detector Acquisition
Detectors measure transmitted X-rays and convert them into electrical signals.
4) Image Reconstruction
The computer reconstructs cross-sectional CT images from multiple projections.
