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.An echo tracking system locks a time window (AUT) to detect an echo in the position of a digital echo (ECHN) obtained from an echo (ECHA) generated by a moving wall receiving an ultrasonic pulse signal with a repetition rate F. This echo tracking system comprises a clearing device (20) defining the time window, a device (22, 28) for detecting the echo position to detect and store the echo (ECHN) time position, and a locking device (18, 28, 30). ) to lock the position of the window to the position of the detected echo. In accordance with the invention, the detection device is sensitive to a flank with a predetermined direction of the echo signal. The invention is useful in the medical field for measuring changes in the position of an interface between two tissues.
