Claim:
An operating method for a swiveling polyplanar imaging system for time-resolved imaging of an object, the swiveling polyplanar imaging system comprising a first and a second imaging planes arranged at an offset angle γ relative to each other and record at a fan angle β, the method comprising: recording a first set of projection images of the object by the first imaging plane from a first set of different angular positions, the first imaging plane being swiveled through at least an angle of φ=180°+β; generating a first data record from the first set of projection images; recording a second set of projection images of the object by the second imaging plane from a second set of different angular positions, the second imaging plane being swiveled through at least the angle of φ=180°+β; generating a second data record from the second set of projection images; storing the first data record and the second data record; creating a third data record by selecting the projection images from the first data record beginning from a starting angle α and the projection images from the second data record so that projection images in the third data record covers at least the angular range of φ; varying the starting angle α from an initial value to a final value α max ; continuously repeating the creating of the third data record and the varying of the starting angle α until the starting angle α has attained the final value α max ; and evaluating a contrast of the projection images in the third data record, wherein three-dimensional images are reconstructed based on the third data record and a contrast of the three-dimensional images is evaluated, and wherein the contrast of the projection images in the third data record and the contrast of the three-dimensional images are evaluated by maximizing an overall grayscale value of the projection images in the third data record and an overall grayscale value of the three-dimensional image.
