Abstract

Verfahren zur bildgebenden Darstellung einer Partie des menschlichen Körpers, insbesondere der weiblichen Brustdrüse, mittels Echosignalen einer auf das Objekt gerichteten Ultraschallstrahlung, wobei die Auswertung von durch einen Echosignalempfänger zeitabhängig empfangenen Echosignalen jeweils auf einer in der Raumrichtung der Primärstrahlung gerichteten Objektachse erfolgt und die Intensität der Echosignale bildgebend ausgewertet wird, wobei bei der bildgebenden Auswertung das Echosignal mit einem weiteren in der entsprechenden Raumrichtung bei fixiert gehaltenem Objekt aufgenommenen bildgebenden Signal einer anderen Signalquelle in räumlicher Zuordnung zusammengefaßt und ausgewertet wird und im Falle der weiblichen Brustdrüse diese zwischen zwei im wesentlichen parallel gerichteten Platten fixiert ist.
