Computer-assisted tomography is an imaging technique used to obtain detailed images of the internal structures of the human body. The word "tomography" refers to the process of creating a two-dimensional image of a slice or section through a three-dimensional object. Synonyms for computer-assisted tomography include computed tomography (CT), computerized axial tomography (CAT scan), and spiral CT. These terms all refer to the same imaging technique, which uses X-rays and computer algorithms to create detailed cross-sectional images of the body. CT scans are commonly used in medical imaging to diagnose a wide range of conditions, including cancer, heart disease, and neurological disorders.
