Assignment of two-dimensional blood flow information to three-dimensional blood vessel system

摘要

Evaluation method for a blood vessel system (5) of a patient by a computer (1), - wherein the computer (1) receives a three-dimensional spatially resolved volume image (4) of the blood vessel system (5) of the patient, - wherein the computer (1) is a two-dimensionally spatially resolved Projection image (6) of the blood vessel system (5) receives, showing a state of the blood vessel system (5) in which a first part of the blood vessel system (5) with a contrast agent (7) is filled and a second part of the blood vessel system (5) not is filled with the contrast agent (7), - wherein the computer (1) determines a representation of the volume image (4) and outputs via a viewing device (10) to a user (11) of the computer (1), - wherein the computer (1 ) in the volume image (4) adjacent, in branchless, each having exactly two ends having portions (8) of the blood vessel system (5) depending on whether they are completely in. Projection in the projection image (6) areas of the blood vessel system (5) filled with the contrast agent (7) are depicted or classified as sections of the first or second type, wherein the computer (1) treats the sections of the first type differently than the sections of the second type in the course of determining the display , characterized in that the sections (8) of the blood vessel system (5) in the volume image (4) are terminated at least on one side by a branch (9).
