A method of operating a pivotable Polyplan imaging system for time-resolved imaging of an object to be examined

The invention relates to an operating method for a pivoting Polyplan imaging system comprising a first and a second under an offset angle γ relative to each other arranged with a fan angle β receiving, imaging plane (A, B) includes, for time-resolved imaging of an examination object with the following steps: S1 receiving the first and second projection images in different angular positions by pivoting the imaging planes (A, B) in each case an angle of at least φ = 180 ° + β to generate an image captured by the first imaging plane (A) the first data set (D1) and one of the second imaging plane (B) captured second data set (D2) and their storage, S2 form a third data set (D3) obtained by selection of projection images from the first data (D1) from a starting angle α and from the second data record (D2), so that the third data (D3) covers an angular range of at least φ, is assembled, S3 performing image reconstruction in the third data (D3) for generating three-dimensional images (optional) S4 variation of the start angle α, S5 repeat of the second to fourth step (S2-S4) so long until the starting angle α has reached its final value α S6 Konstrasts evaluation of projection images of the third data set (D3) and / or in the third step (S3) in the case of carrying out the three-dimensional images produced.
