The simulation shows an X-ray source and detector orbiting a synthetic tissue cross-section, accumulating one angled projection at a time into a growing sinogram, then approximately back-projecting those projections to reconstruct the original density pattern.
Pick a phantom shape, adjust rotation speed with the slider, and watch the sinogram fill in as the source-detector pair sweeps around; pause or rebuild with a new phantom at any time using the buttons.
Phantom select, rotation speed slider, play/pause and rebuild buttons
A single point of dense tissue traces a sine-wave curve across a real sinogram as the scanner rotates around it — that's literally where the word 'sinogram' comes from.
