title: Computed tomography with geometrical enlargement.
abstract: Third generation CT scanners perform examinations of small objects without employing all the detectors. Geometrical enlargement solves this problem by moving the tube-detector assembly according to the size of the object to be scanned; this improves spatial resolution, reducing both the tube current and the skin dose. Such an application for pediatric CT and small objects is of particular interest.
