Definition (Myers):a series of x-ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body. Also called CAT scan.
Definition (alternative): Computed tomography (CT) is a medical imaging method employing tomography. Digital geometry processing is used to generate a three-dimensional image of the inside of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation. *link
Contextual explanation:
The scan examines the brain by taking x-ray photographs to obtain information about the brain's condition, and possibly find any damages in the brain. For example, if a soldier was shot in the head, through the CT Scan, doctors can find out where the bullet hit the brain, and which part of the brain was damaged.
