See helical CT.
Modified conventional computed tomography (CT) technique utilizing continuous scanning. For a spiral CT, the x-ray tube continuously revolves around the patient. This produces a three-dimensional reconstruction and helps doctors detect nodules that are too small to be seen on a conventional x-ray.
low-dose multidetector spiral computed tomography (CT) is an imaging technique that can screen asymptomatic, high-risk individuals for small lung nodules before they appear on traditional x-rays.
Also called helical CT. Variety of CT (most newer machines) where, in stead of taking one by one slice, the patient is fed slowly and evenly into the gantry (see gantry) while the X-ray tube and detector move in a continuous circle. Instead of separate slices this will result in a long spiral where each new "slice" starts where the previous "slice" ends.
a special scanner that takes cross-sectional pictures around the body. See also computerized tomography.
