Method and apparatus for adjusting a scanning region in a computed tomography system

A method and an apparatus are provided for adjusting a scanning region of a computed tomography (CT) scanner. At least one edge point of a set-point scanning region on a patient examination table associated with the CT scanner is indicated by hand signals of a user. Via a distance sensor, mounted at a reference point of the patient examination table, a distance from the at least of edge point to the reference point is measured. From the measured distance, the position of the at least one edge point relative to the patient examination table is determined, and a corresponding edge of a CT scanning region of the CT scanner is conformed to the derived position.
