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.
An imaging method for computer-assisted evaluation of projected object trajectories of volume elements, which are obtained from computer-tomographic measurement, comprising arranging into a projection matrix the projected object trajectories in a preknown sequence and as tracks of the respective volume elements and iterating the following steps until an adequate reconstruction quality has been achieved:
An arrangement for the computer-assisted evaluation of projected object trajectories obtained from computer-tomographic measurement, comprising a memory for a projection matrix with tracks contained therein, a selector for the selection of certain tracks from the projection matrix, a memory for a reconstruction picture, a device for the positionally-true back-projection of tracks into reconstruction elements, a device for removing tracks from the projection matrix and a device for determining the quality of the reconstruction.
