COMPUTERIZED TOMOGRAPHY

Computed tomography has a tube that gives x-rays and detectors that hold these rays. The patient is in between the two. Thus, the x-rays are held by the detectors after passing through the patient.
Since the atomic densities of the tissues of the body are different, the x-ray held by each tissue is different and thus tissue images are created. The tubes and detectors rotate 360 degrees around the patient, displaying a section of that part of the body.
