Generating an at Least Three-Dimensional Display Data Sheet

An x-ray apparatus for generating an at least three-dimensional display data set of a time parameter relating to chronological spreading of a contrast medium introduced into a vessel system, wherein a series of chronologically successive x-ray images of digital subtraction angiography from at least two different projection directions showing the chronological spreading of the contrast medium is used, the x-ray apparatus comprising:

• a control device configured to:
• determine a three-dimensional position for at least one correspondence point, correspondence region, or correspondence point and correspondence region defined, in each case, in at least one x-ray image of a projection direction;
• for each three-dimensional position, determine a time parameter assigned to the three-dimensional position, the determination of the time parameter comprising an evaluation of time-intensity curves assigned to the correspondence points or the correspondence regions over the series;
• and
• display the at least three-dimensional display data set formed from the three-dimensional positions with the assigned time parameters

In a non-transitory computer-readable storage medium that stores instructions executable by a computer device to generate an at least three-dimensional display data set of a time parameter relating to chronological spreading of a contrast medium introduced into a vessel system, wherein a series of chronologically successive x-ray images of digital subtraction angiography from at least two different projection directions showing the chronological spreading of the contrast medium is used, the instructions comprising:

• determining a three-dimensional position for at least one correspondence point, correspondence region, or correspondence point and correspondence region defined, in each case, in at least one x-ray image of a projection direction;
• for each three-dimensional position, determining a time parameter assigned to the three-dimensional position, the determining of the time parameter comprising evaluating time-intensity curves assigned to the correspondence points or the correspondence regions over the series;
• and
• displaying the at least three-dimensional display data set formed from the three-dimensional positions with the assigned time parameters.
