Abstract
The invention relates to a method for three-dimensional representation of a moving structure by a tomographical method. Projection images are recorded by an image recording unit during a rotational run from recording angles between a start angle and an end angle, with a three-dimensional image data reconstructed from the projection images, with a first perfusion measurement with a first contrast agent injection and a first rotational run and with a further perfusion measurement with a further contrast agent injection and a further rotational run, which is started after the preceding perfusion measurement has concluded, with the start time and/or the start angle of the additional rotational run deviating from one another in respect of the time of the contrast agent injection. The method enables a functional three-dimensional time-resolved imaging of perfusion processes with the aid of flexible C-arm x-ray devices, which allow a functional imaging in an interventional environment.
