In computed tomography, there is a tube that gives out x-rays and detectors that hold these rays. The patient is between these two. Thus, the x-rays are captured by the detectors after they pass through the patient. Since the atomic densities of the tissues of the body are different, the x-rays held by each tissue are different and thus tissue images are created.
Tubes and detectors rotate 360 degrees around the patient, displaying the cross-section of that part of the body.
