Method And Medical Apparatus For Measuring Pulmonary Artery Blood Flow


In a method and apparatus for examination and evaluation of a blood flow in a pulmonary artery of a patient, measurement data are recorded, from which at least a part of the blood flow in the pulmonary artery is able to be re-constructed at least two-dimensionally in a plane defined by a longitudinal axis of the pulmonary artery and by an anterior-posterior direction, including at least at several diastolic points in time in the course of a heart cycle, after a closure of the pulmonary valve. The number of diastolic points for which an asymmetry in relation to the longitudinal axis of the pulmonary artery in the anterior-posterior direction exists is determined. A measure is then determined that characterizes how long, after the closure of the pulmonary valve, the aforementioned asymmetry exists.
