Abstract:
A method for radiographic imaging is described. Radiographic raw images of an object are generated by an imaging system comprising an X-ray source and an X-ray detector and moving along a given trajectory during an acquisition process of the radiographic images. During the generation of the radiographic raw images displacement data describing the displacement of the moving object are generated by means of a sensor arrangement and a control unit connected with the sensor arrangement. Finally views of the object are produced by image processing of the radiographic raw images in the control unit wherein the displacement data are used for compensating the motion of the object. For the compensation of the motion, the object is treated as stationary and the actual trajectory is replaced by a virtual trajectory resulting in a spatial relation between the stationary object and the imaging system on the virtual trajectory that corresponds to the spatial relation between the displaced object and the imaging system on the actual trajectory.
