1. A method for analyzing a plurality of two-dimensional projection images of a three-dimensional examination object, comprising: assigning a plurality of image times and imaging parameters to the projection images by a computer, wherein each of the image times corresponds to an acquisition time when a respective project image is captured; combining the projection images into a plurality of reconstruction groups based on the assigned image times by the computer; determining a plurality of three-dimensional reconstructions of the examination object based on the projection images assigned to the reconstruction groups by the computer; determining a plurality of reconstruction times based on the image times assigned to the projection images in the reconstruction groups by the computer; assigning the reconstruction times to the three-dimensional reconstructions for generating a temporal sequence of the three-dimensional reconstructions by the computer; and analyzing the projection images as a function of the temporal sequence of the three-dimensional reconstructions by the computer, wherein the projection images are digital subtraction angiography images that are determined by subtracting native images captured at acquisition times with reference images assigned identical imaging parameters with the native images and the image times of the digital subtraction angiography images correspond to the acquisition times.
