Abstract:
1. A method for a three-dimensional representation of a structure moved or influenced by a periodic process, comprising: rotating an imaging unit a predefined angular range of rotation about a structure, wherein N number of rotations comprising at least two rotations are executed in succession, wherein starting angles of the rotations have an offset with regard to one another based upon a predefined differential angle, wherein the predefined differential angle comprises the angular range of rotation divided by the N number of rotations; recording a plurality of projection images for each N number of rotations from different projection angles between a starting angle and an end angle during rotation of the imaging unit in accordance with the predefined differential angle; for a selected point in time t combining into an image series of during the time interval of t reconstructing a three-dimensional image data record based upon projection images assigned to the phase range, wherein the three-dimensional image data record shows the structure in the phase range of the periodic process.
