Determination of a multi-energy image

摘要

A method is disclosed for determining a multi-energy image via an x-ray device, including an x-ray source and an x-ray detector. The method includes a temporal sequence of individual steps. A first contrast agent-assisted image of an object area is first recorded with a first energy. Then a second contrast agent-assisted image of an object area is recorded with a second energy. A third recording of a third contrast agent-assisted image of the object area is now made with the first energy. By taking the temporal change in the contrast agent signal into account between the first and the third image, a multi-energy image is finally determined by means of the three recordings.
