Computed Tomography (CT) is a form of cross sectional imaging. An x-ray tube with a thin beam rotates around the patient obtaining multiple images, which are relayed to a computer that reconstructs the image. CT allows one to see the internal structure of the body and has higher resolution than routine radiography. Indications for CT imaging include evaluation of the brain or other structures of the head, thoracic imaging, and for computerized radiation therapy treatment planning.
