Human heart ejection fraction e.g. left ventricular ejection rate, determining method for use in hospital, involves determining ejection fraction by comparing initial value and contraction values of initial and contraction analysis regions

摘要

The method involves determining initial and contraction analysis regions bordered by heart sections in image representation of measured values for initial and contraction condition of hearts, respectively. Initial and contraction values are determined for respective regions, where a respective parameter is detected for image sections in the regions. An ejection fraction of heart is determined by comparing initial and contraction values. The respective parameter is a measure for a contrast medium effect during a contrast medium based imaging in the image sections, during initial or contraction condition of the heart. Independent claims are also included for the following: (A) a computer device for implementing a method of determining an ejection fraction of a heart (B) a device for contrast medium based imaging for the heart.
