Abstract
Et ekkosporingssystem låser et tidsvindu (AUT) for å detektere et ekko i posisjonen til et digitalt ekko (ECHN) som er oppnådd ut fra et ekko (ECHA) som er frembrakt av en bevegelig vegg som mottar et ultralydpulssignal med en repetisjonsfrekvens F . Dette ekkosporingssystem omfatter en klargjø-ringsanordning (20) som definerer tids-vinduet, en anordning (22, 28) for deteksjon av ekkoets posisjon for å detektere og lagre ekkoets (ECHN) tids-posisjon, og en låseanordning (18, 28, 30) for å låse vinduets posisjon til posisjonen av det detekterte ekko. I overensstemmelse med oppfinnelsen er deteksjonsanordningen følsom for en flanke med forutbestemt retning av ekkosignalet.Oppfinnelsen er nyttig på det medisinske område for måling av endringer av posisjonen av en grenseflate mellom to vev.
