Abstract
The invention is directed to a method and a device for separate three-dimensional presentation of arteries and/or veins of a vessel system in a part of the body of a vertebrate by a rotation computer tomography. A masking run of the tomograph is undertaken without contrast media around the part of the body. Then two filling runs with contrast media are executed, with the venous phase of vessel contrasting during the first filling run occurring during the arterial phase of vessel contrasting of the second filling run and vice-versa. The data from the first and second filling run is combined into data sets from the arterial or the venous phases of the vessel contrasting of the filling runs. The data of the masking run is subtracted from the combined data sets to obtain final data sets for a three-dimensional presentation of the arterial or the venous vessel system.

17. A method for generating a data set of an artery of a vessel system in a part of a body of a vertebrate by a rotation computer tomography, comprising:
-
performing a masking run by the tomograph without an injection of a contrast media around the part of the body; recording a data of the masking run; performing a first filling run by the tomograph with a first injection of the contrast media around the part of the body, the first filling run comprising an arterial phase part and a venous phase part; recording data of an arterial phase of vessel contrasting of the first filling run during the arterial phase part of the first filling run; performing a second filling run by the tomograph with a second injection of the contrast medium around the part of the body, the second filling run comprising an arterial phase part occurring in the venous phase part of the first filling run and a venous phase part occurring in the arterial phase part of the first filling run; recording data of an arterial phase of vessel contrasting of the second filling run during the arterial phase part of the second filling run; combining the data of the arterial phase of vessel contrasting of the first filling run and the data of the arterial phase of vessel contrasting of the second filling run into a combined data set; subtracting the data of the masking run from the combined data set to generate the data set of the artery of the vessel system; and using the data set of the artery of the vessel system in a humanly perceptible manner. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)

26. A method for generating a data set of a vein of a vessel system in a part of a body of a vertebrate by a rotation computer tomography, comprising:
-
performing a masking run by the tomograph without an injection of a contrast media around the part of the body; recording a data of the masking run; performing a first filling run by the tomograph with a first injection of the contrast media around the part of the body, the first filling run comprising an arterial phase part and a venous phase part; recording data of a venous phase of vessel contrasting of the first filling run during the venous phase part of the first filling run; performing a second filling run by the tomograph with a second injection of the contrast medium around the part of the body, the second filling run comprising an arterial phase part occurring in the venous phase part of the first filling run and a venous phase part occurring in the arterial phase part of the first filling run; recording data of a venous phase of vessel contrasting of the second filling run during the venous phase part of the second filling run; combining the data of the venous phase of vessel contrasting of the first filling run and the data of the venous phase of vessel contrasting of the second filling run into a combined data set; subtracting the data of the masking run from the combined data set to generate the data set of the vein of the vessel system; and using the data set of the vein of the vessel system in a humanly perceptible manner. - View Dependent Claims (27, 28)

29. An apparatus for generating an image data set of an artery of a vessel system in a part of a body of a vertebrate, comprising:
-
a rotation computer tomography that performs; a masking run without an injection of a contrast media around the part of the body to record a data of the masking run, a first filling run with a first injection of the contrast media around the part of the body to record data of an arterial phase of vessel contrasting of the first filling run during an arterial phase part of the first filling run, and a second filling run with a second injection of the contrast media around the part of the body to record data of an arterial phase of vessel contrasting of the second filling run during an arterial phase part of the second filling run; and a computation device that; combines the data of the arterial phase of vessel contrasting of the first filling run and the data of the arterial phase of vessel contrasting of the second filling run into a combined data set, and subtracts the data of the masking run from the combined data set to generate the image data set of the artery of the vessel system. - View Dependent Claims (30, 31, 32)
