Abstract
Disclosed are an imaging method and an arrangement for the computer-assisted evaluation of projected object trajectories obtained from a computer-tomographic measurement. According to the inventive method, the trajectories are arranged in a previously known sequence into a projection matrix as traces of the respective voluminous elements, and the following steps are iterated until a sufficient reconstruction quality has been attained; (a) at least one of the traces is selected; (b) a reconstructed element that is true to the original position is formed from each of the selected traces so as to be added to a reconstructed image; (c) the selected traces are removed from the projection matrix.
