Abstract
A data set describing a vascular system in three dimensions is pre-specified to a computer. A section of the vascular system is selected. With the aid of the data set describing the vascular system in three dimensions, the computer calculates a length of the selected section. A sequence of images of the vascular system is pre-specified to the computer, wherein a time is assigned to each image. One image respectively of the sequence is defined as a start image and as a stop image. With the aid of the length of the selected section and the times assigned to the start image and the stop image, the computer determines a velocity and outputs the velocity together with the selected section to a user. The operating method can be integrated in particular into the clinical workflow.

23. A method for calculating a flow velocity of a fluid in a vascular system, comprising:
-
pre-specifying a data set to a computer that describes the vascular system in three dimensions;
selecting a section of the vascular system that has a start and an end;
calculating a length of the selected section via the data set;
pre-specifying to the computer a sequence of images of the vascular system;
assigning a point in time to each image;
selecting an image of the sequence of images as a start image and an image of the sequence of images as a stop image;
calculating the flow velocity from the length of the selected section and the points in time assigned to the start image and the stop image; and
outputting the blood flow velocity together with the selected section to a user. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 40, 41)

39. A method for operating a medical imaging system, comprising:
-
receiving a selection of a section of a vascular system from a user;
adjusting positions of a recording arrangement to record the selected section;
receiving a preliminary image of the selected section from the recording arrangement;
outputting the preliminary image of the selected section to the user via a display device;
waiting for an input of a value numeral by the user;
archiving the value numeral and the preliminary image if the value numeral lies in a predefined range of values;
recording a sequence of images and the recording times thereof if the value numeral lies outside of the predefined range of values; and
archiving the sequence of images, wherein the images show the through-flow of a fluid through the selected section.
