Abstract:
A computed tomography apparatus comprising:a gantry; an x-ray source having a focus from which an x-ray beam emanates and a radiation detector on which said x-ray beam is incident, said radiation detector having a plurality of rows of detector elements; a patient support adapted to receive an examination subject thereon in said x-ray beam, said patient support having a longitudinal axis; said gantry and said patient support being tiltable relative to each other into a tilted state wherein a system axis and said longitudinal axis are inclined relative to each other and wherein, in said tilted state, said patient support and said gantry are linearly adjustable relative to each other to generate a relative movement in the direction of said system axis between said gantry and said patient support; and at least said focus being displaceable around said system axis coordinated with said relative movement in the direction of said system axis between said gantry and said patient support, with said examination subject disposed in said x-ray beam, to conduct a spiral scan, and said radiation detector generating data from which tomograms of slices of an examination subject are computed which are inclined relative to said longitudinal axis of said patient support.
