Computed tomography. Computed tomography (CT) scanning, also known as, especially in the older literature and textbooks, computerized axial tomography (CAT) scanning, is a diagnostic imaging procedure that uses x -rays to build cross-sectional images (slices) of the body Datortomografi, oftast förkortat DT alternativt CT (av engelskans computed tomography ), även kallad skiktröntgen, är en vidareutveckling av den vanliga röntgenapparaten (slätröntgen). Inom medicinsk diagnostik används datortomografi för att avbilda patienten i tre dimensioner, istället för som vid slätröntgen erhålla en tvådimensionell bild där.
