1. An X-ray imaging method for time-resolved three-dimensional (3D) representation of at least one hollow organ of a person, the method comprising:
obtaining a first time length that corresponds to a person-specific time length for a contrast agent to flow from a defined contrast-agent injection location for the person to a defined proximal location of the at least one hollow organ;
obtaining a second time length that corresponds to a person-specific time length for the contrast agent to flow from the defined proximal location to a defined distal location of the at least one hollow organ;
during a first acquisition phase, producing a first sequence of projection images, wherein each projection image in the first sequence at least partially represents the at least one hollow organ under a different respectively defined projection direction, wherein the first acquisition phase begins the first time length after an injection start time for injecting the contrast agent at the contrast-agent injection location, and a duration of the first acquisition phase equals the second time length; and
producing a time-resolved 3D reconstruction of the at least one hollow organ based on the projection images in the first sequence.
