In computerized tomography, there is a tube that gives x-rays and detectors that capture these rays. The patient is in between these two. Thus, the x-rays are captured by detectors after passing through the patient. Since the atomic densities of the body's tissues are different, the x-ray captured by each tissue is different and thus tissue images are created.

The tube and detectors rotate 360 degrees around the patient and display a cross-section of that part of the body.
