  • Patent number: 12232901
    Abstract: In an X-ray imaging method, a first time length that corresponds to a time length for a contrast agent to flow from a defined contrast-agent injection location to a defined proximal location of a hollow organ, and a second time length that corresponds to a time length for a contrast agent to flow from the proximal location to a defined distal location of the hollow organ are obtained. During a first acquisition phase, a first sequence of projection images is produced. Each projection image at least partially represents the hollow organ under a different respectively defined projection direction. The first acquisition phase begins the first time length after an injection start time for injecting the contrast agent, and a duration of the first acquisition phase equals the second time length. A time-resolved three-dimensional reconstruction of the hollow organ is produced based on the projection images in the first sequence.
