An angiographic examination method for examining an organ, vascular system or other regions of a patient is proposed. Projection images are acquired by an angiography system having an X-ray tube assembly and an X-ray image detector applied to ends of a C-arm, a patient table having a tabletop for carrying the patient, a system control unit, an imaging system and a monitor. Projection images are generated by rotational angiography from a plurality of projection angles. The projection images are subjected to a pre-processing of an FDK reconstruction, the result of which is filtered by a noise-reduction method. A predetermined number of dynamic, iterative reconstruction steps is carried out. Time attenuation curves are reconstructed, which are modeled with a weighted sum of linear basis functions.
