Zerlegung der Magnetisierung in Konfigurationen

  • Chapter
Magnetresonanzbildgebung

Zusammenfassung

In früheren Kapiteln wurde die Bewegung des Vektors der Gesamtmagnetisierung unter dem Einfluss von RF-Pulsen und Gradientenfeldern beschrieben. Die \( \vec k \)-Ebene (oder der \( \vec k \)-Raum im Falle eines 3D-Scans) diente zur Beschreibung der verschiedensten Scanverfahren. Mittels Verfolgung des Pfades durch den \( \vec k \)-Raum konnten viele Eigenschaften eines Scanverfahrens und (grundlegende) fundamentalen Artefakte, wie jene durch T 2-oder T 2*-Abfall und Resonanzoffset beschrieben werden. In diesem Kapitel wird gezeigt, dass sich zusätzliche Informationen dadurch gewinnen lassen, dass man den Magnetisierungsvektor in „Konfigurationen“ (Gruppen freier Spins mit gleicher dynamischer Magnetisierungsentwicklung) zerlegen und diesen dann bezüglich seines Dephasierungszustandes analysieren kann.
