Computed tomography mechanism

What is the mechanism of a CT scan?
How a CT system works.
A motorized table moves the patient (Figure 3) through a circular opening in the CT imaging system.
As the patient passes through the CT imaging system, a source of x rays rotates around the inside of the circular opening.
A single rotation takes about 1 second._{Sep 28, 2020}.
What is the physics behind CT scans?
In the particular case of CT, the emitter of x-rays rotates around the patient and the detector, placed on diametrically opposite sides, picks up the image of a body section (beam and detector move in synchrony).
Unlike x-ray radiography, the detectors of the CT scanner do not produce an image._{Oct 23, 2023}.
