Abstract:
1. A method for recording an examination object using an x-ray recording system having an x-ray source and an x-ray detector rotatable about a common axis of rotation, comprising: displacing the x-ray detector in a first direction to enclose a first angle k between a perpendicular bisector from the x-ray source to the x-ray detector and a plane running through the x-ray source and containing the common axis of rotation, wherein the first angle k≠0; recording a first plurality of x-ray images during a first rotation about the common axis of rotation in a first plurality of angular positions of the x-ray source and the x-ray detector displaced in the first direction; displacing the x-ray detector in a second direction to enclose a second angle m between the perpendicular bisector and the plane, wherein the second angle m≠0 and is on an opposite side from the first angle k; and recording a second plurality of x-ray images during a second rotation about the common axis of rotation in a second plurality of angular positions of the x-ray source and the x-ray detector displaced in the second direction, wherein starting points of the first and the second rotations about the common axis of rotation are differed by an angle of displacement β wherein the starting points and finishing points of the first and the second rotations about the common axis of rotation are spanned by an angle π+β wherein the angle of displacement wherein d is a fan angle of the detector spanned by the x-ray detector in relation to the x-ray source.
