Caption: Doctor studying film sheet of computed tomography (CT) scans of various sections through the human head. More films are shown in background. CT scanning is regarded as the most important advance in diagnostic imaging since Roentgen recorded his first X-ray images at the end of the 19th century. Access to CT equipment has greatly speeded up the diagnosis of a number of serious conditions, especially cancer & stroke. Various CT sections may be combined to produce 3-D imagery, used in planning surgery. CT is used to enhance radiotherapy, to accurately target the radiation dose & so help minimise the damage to surrounding healthy tissue.
