Abstract

Die bei einer kernspintomographischen Untersuchung gemessene neuronale Aktivierung folgt einem Protokoll, das den zeitlichen Ablauf der Stimuli wiedergibt. Bei der Korrelationsanalyse nimmt die Empfindlichkeit für Änderungen der Signal-Response-Form nach dem Stand der Technik mit jedem Aktivierungscyclus ab. Erfindungsgemäß werden bessere Auswertungsergebnisse bei der Korrelationsanalyse mit einem Detrending-Verfahren mit einem Computer zur Auswertung von Daten von Kernspintomographen erzielt, der mit Mitteln zur Auswertung ausgestattet ist, die nach einem Sliding-Window-Verfahren eine Anzahl von n Datenwerten zur Korrelationsanalyse heranziehen, die konstant bleibt, wobei mit Fortschreiten der Datenmessung der jeweils älteste Wert entfällt und der jüngste Datenwert zur Berechnung herangezogen wird.
